The effect of corner flow is investigated in an inclined square cavity numerically. Both clear domain and porous substance are considered in the cavity. The study is conducted under distributed heating and cooling arrangement applied on the four walls. This numerical study is carried out on a ventilated cavity providing entry and exit at diagonally opposite corners. On fluid dynamics, effects of various flow parameters like Richardson number (Ri = 0.1-20), Reynolds number (Re = 10-200), cavity inclination angle (γ = 0-180°), Darcy number (Da = 10-4-10-7) and porosity (ε = 0.3-1.0) are analyzed systematically. Streamlines, isotherms and average Nusselt number are utilized for exploring heat transfer of the cavity.Keywords

The impact of magnetic-!eld induced force on buoyant "ow in lid-driven cavity is addressed in this work. Two sides of the cavity are moving in opposite directions. The temperature of heating element located on the bottom wall is varied linearly and is mirrored about the mid-point of the wall. The convective heat transfer in the cavity is analyzed systematically using an in-house CFD code. The fundamental aspects of different "ow regimes, the strength and inclination of magnetic !eld are explored. The obtained results reveal strong in"uence of Ri and Ha on the heat transfer characterization.Keywords

The external flow based mixed convection has wide uses in many applications. The present numerical investigation is carried out on a ventilated porous cavity providing fluid flow diagonally. Two heating elements and cooling elements are placed in the middle of the walls of the cavity. The simulation is carried out using an inhouse code for a range of parameters such as different flow regime (using Richardson number Ri= 0.120), Flow velocity (using Reynolds number Re= 10200), permeability (using Darcy number Da= 10 10 ) and porosity ( = 0.30.8) of the porous media. The -7 -3 ε results are presented using isotherms, streamlines and average Nusselt number. The obtained results show a strong parametric dependence of fluid flow and associated heat transfer phenomena. An exception to the usual trends of heat transfer characteristics of clear and porous domain, the heat transfer of porous domain increases due to corner flow.Keywords
