CFD analysis of natural convection heat transfer in a static domestic refrigerator

Abstract Refrigerating compartment with and without shelves is designed for analyzing the air flow temperature distributions by using Simulation software Ansys work bench 14. Comparing results of inside refrigerating shelves. Here considered as obstacles refrigerator freezer a 2D rectangular enclosure one side assumed evaporator wall (cold wall) other Door (warm wall). Inside cabin takes natural convection. Temperature observed in same compared. In convection heat transfer happens between internal walls radiation, conduction Air flows downward near cold moves upward warm due to density variation. As result, stratification was compartment. Evaporator maintains colder region door has higher temperature.
