In designing of condensers, the prediction of pressure drop is as important as the prediction of heat transfer coefficient. Modeling of two phase flow, particularly liquid – vapor flow under diabatic conditions inside a horizontal tube using CFD analysis is difficult with the available two phase models in FLUENT due to continuously changing flow patterns. In the present analysis, CFD analysis o...

In presented work, researchers have used efficiency defect as a tool for checking the utility of different refrigerants in Vapour compression refrigeration system. A mathematical model simple system is created. Using first law analysis and exergy calculated various components individually whole vapour well. It found that R1234yf has highest value system, whereas R134a least Variation with evapo...
