Thermal Performance and Fuzzy Logic Modelling for Wavy Twisted Tape Inserts in Single Phase Flow
The designing of heat exchangers is quite complicated, as it needs correct analysis of heat transfer rate and pressure drop estimations apart from issues such as long-term performance and the economic aspect of the equipment. In order to obtain above objective the current experimental investigation has been carried out which shows that heat transfer enhancement take place with increase in turbulent flow where Reynolds number varies from 4000 to 9500 and turbulent flow is developed due to twist tape wavy inserts , the twists ratio are 8.33, 9.79 & 10.42. Performance parameter like pressure drop and heat transfer coefficient is calculated. The obtained results are compared with various combinations such as smooth tube versus twisted tape inserts & plain tape inserts. The above obtained results are studied using a fuzzy inference system named Mamdani and used to expect the output membership functions be fuzzy sets.
