From the dawn of civilization water and man are related to each other. Man lives on water but, unfortunately, cares little for it. Time has come to understand the importance of water on the earth and stop indiscriminate use of the same. Conservation of water is the need of the hour. Human Development Index and use of water are inter-related. India has different rates of precipitation in different parts of it. For example, Rajasthan with 8% of the country's population has only 1% of the total water resources of the country whereas Bihar with 10% of the country's population has 5% of water resources. A large amount of area in this country is affected by drought. The role of major dams has also been discussed.Keywords

The erosion of the river bank is a complex mechanism and sediment particles are subjected to a number of forces. Among those forces, force of cohesion between the particles plays a very significant role, and, until now, not much progress has been made to analyze the cohesive force in a comprehensive manner. It is imperative that a particle is surrounded by a family of similar sort of particles and ail are bounded together under this force of cohesion. In this article, a review of the already existing equations available for determination of the escape velocity of a particle on the riverbank is made and a new equation has been suggested. The proposed equation takes into account the micro-level variations in the system comprising of a host of particles in dynamic equilibrium.Keywords

The present work stud1ies the effect of viscous dissipation on the limiting value of Nusselt number for a laminar shear-driven flow of Newtonian fluid between two infinite parallel plates. In order to make the flow occur, both the plates are assumed to move in the axial direction at a constant speed. The study considers the flow to be hydro-dynamically fully developed, while both the plates are kept at unequal constant temperatures. A few assumptions, which are commonly employed in the literature, are considered only to obtain the solution in an analytical framework. In order to delve deep into the effect of viscous hearting on the thermal transport characteristics of forced convective heat transfer, the closed-form expressions of limiting Nusselt numbers are evaluated in terms of the Brinkman number. The study concentrates on the viscous dissipation with the heat transfer characteristics, and, thus, emphasis is given to the viscous heating arising out of the movement of both the plates relative to each other. The effects of the viscous heating and degree of asymmetric wall heating on the heat transfer characteristics are found to be significant following the variation of the Nusselt number. The variation of Nusselt number portrays the existence of the point of singularities at different locations. The point of singularity, as seen on the variation, is the outcome of the equilibrium between the heat generated owing to the viscous heating and the heat supplied by the wall.Keywords

The riverbank erosion mechanism is very complex, and sediment particles on the riverbank are subjected to a number of forces. Among those forces, the force of cohesion between the particles plays a very significant role. Also important is the viscous force coming into play due to the presence of water-bridge between each pair of particles. Frequency of bank failure is proportional to the erosion rate and bank failure causes flood. Every particle is surrounded by a family of similar particles, and all are bound together under this force of cohesion. In this paper, a recently published analytical model named the ''Truncated Pyramid Model'' for the arrangement of particles has been used, and the general equations for the impending acceleration, as well as the escape velocity, of a particle have been modified to accommodate the viscous force. The effect of the forces on a soil particle is presented graphically for pure water. The graphs depict the deviation from results of the previously published research work due to the consideration of the viscous force. The escape velocity of a particle is the key to determining the other parameters related to riverbank erosion, such as the entrainment rate and the volumetric rate of bank erosion.Keywords

Mechanism of erosion along a riverbank is full of complexity in nature. Among many forces on the sediment particles along a riverbank, cohesive and viscous forces are predominant. A family of similar particles surrounds every particle and they are bound together under the action of cohesive and viscous forces. In this paper, sediment particles are arranged according to the truncated pyramid model and a general equation for the escape velocity of a particle has been suggested. It is observed that this escape velocity is very much dependent on the inter-particle separation distance for a given liquid bridge volume between a pair of adjacent particles. Determination of the escape velocity is an approach to quantification of volumetric erosion rate. In this paper, a comparison has been made between the values of the escape velocity obtained from a previous study considering only cohesive force and the values of the escape velocity obtained considering both cohesive and viscous forces for a particular liquid bridge volume. All the other parameters remain the same for both the cases. It has been shown that the values of the escape velocity obtained in the present study considering both cohesive and viscous forces increase a considerable amount than the values obtained in the previous study considering cohesive force only for the same input parameters.Keywords

The present work investigates turbulent supercritical (Froude Number>1) bend flow through an open channel. The CFD-based model, ANSYS FLUENT version 13.0, is used to solve the threedimensional (3D) continuity and Navier-Stokes equations. The standard k =ε turbulence model is considered for the investigation. The model is applied to the channel bend geometry as described in a published experimental work. Results in the form of velocity profiles and non-dimensional water depths are obtained and compared with the already published experimental findings. The results obtained through the present work as compared to the published ones indicate that three-dimensional modelling technique plays a significant role in the entire endeavour and, thus, the three-dimensional approach makes highly-improved predictions. Also, the three-dimensional simulation indicates the existence of a nonlinear gradient of water depth as the water flows through the bend.Keywords

In this paper it has been shown that the cohesive force binds the particles on a riverbank. The escape velocity of the particles is a function of the inter-particle distance, the mean radius of the particles and the volume of water entrapped between them. The escape velocity is the velocity required by a particle to get separated from the riverbank. It helps in determination of other relevant parameters like volumetric rate of bank erosion, entrainment rate and so on. Unlike the previous research here light has been thrown on the cohesive force between the adjacent particles in a deterministic manner. The influence of a gradual increase in the volume of water bridge on the escape velocity of a particle has also been studied.
An analysis of the data has been made to find the level of significance of the input parameters. This includes a regression analysis for calculation of the residual values between the predicted and the calculated escape velocities. Corresponding graphs have also been plotted to present these variations pictorially.

A particle on a riverbank is subjected to a number of forces. Among them, cohesive and viscous forces are predominant, hi this present work, an analytical model called the Truncated Pyramid Model has been used to quantify the effect of the viscous force on the particles on a riverbank and the dynamic influence of water entrapped between the particles. For this, the existing model has been suitably modified to incorporate the viscous effect. The whole mechanism involves a good number of variables namely inter-particle distance, separation speed, liquid bridge volume, radius of the sphere particle and radius of the wetted area. In this work, cohesive and viscous force components have been resolved along horizontal and vertical directions and two separate differential equations have been established for horizontal and vertical components of separation speed that is varying with time. Variation of separation speed with separation distance for a particular liquid bridge volume at different times has been evaluated thereafter.

As the technology advances by leaps and bounds, engineering education needs to keep pace with it. Students pursuing engineering education require making themselves fit for the industry. This is not possible unless the faculty members are knowledgeable enough about what is happening around them. At the same time, population is expanding and that aggravates the problem to a great extent. A recent study finds a meager 6% of the total engineering graduates in India to be actually employable. This is an alarming situation as it will affect the corporate world as well as the socio-economic fabric of the country. It is the need of the hour to search for a probable solution.References

The phenomenon of erosion of a riverbank is extremely complicated and various forces act on bank sediments. Cohesive force between these grains and the force due to seepage of water play an important role among those forces. The present work uses the ‘‘Truncated Pyramid Model (TPM)’’ for the arrangement of grains and proposes generalized equations for calculating escape velocity under cohesion and seepage. The effect of seepage force along with the cohesive force has been studied for different degrees of exposure (fully exposed, half exposed and fully submerged) and compared with the previous study where only the force of cohesion was taken into account. The change in escape velocity due to seepage force for different degrees of exposure has been determined in this paper for three different grain sizes (300 µm, 400 µm and 500 µm of radius) along with different inter-particle distances.Keywords

The present work deals with an experimental analysis of the performance of a direct expansion coil under various operating conditions. Behaviour of the cooling coil vis-à-vis the input parameters and the psychrometric properties is assessed with the help of experimentation with changing ambient conditions and graphical presentation of the results. Results depict an optimum value of the by-pass factor indicating the best performance of the coil in both spring and summer. There is an upward trend of the by-pass factor with a gradual rise in the air temperature at different inlet openings. Dependence of the cooling coil performance on volume flow rate and climatic variation is found to be quite significant and needs to be kept in mind in practice.Keywords

Oscillating hydraulic jump experiments were conducted by increasing the temperature of water from minimum to maximum within a range of measurement. By varying temperature from 32-40°C, different jump characteristics were observed and noted. The varying temperature was measured throughout the jump profiles and dependence of jump parameters with varying temperature is measured and quantified. This study may find applications where a changing stream water temperature significantly affects the jump characteristics.Keywords
