CFD simulation of velocity and temperature distribution inside refrigerator compartment

Abstract

The utility of a household fridge is to preserve the food eminence. Eminence of food unswervingly be reliant on temperature and air velocity distribution esoteric the stowing compartments. Disapproving temperature for food preservation will cause food to worsen or dwindling. Proper temperature distribution as well air flow keep the food fresh in the food chambers. This work presents the air flow and temperature distribution through natural convection warmness switch in severally modeled freezer is studied. The freezer and refrigerant compartments is studied for three configurations. The freezer and refrigerant compartments is studied for three configurations. In initial configuration using Plate-evaporator with rectangular finned surface and In second configuration Plate-evaporator while not finned surface and In third configuration Plate-evaporator with perforated finned surface. The simulations are carried out using ANSYS 16 work bench computational fluid dynamics software program package. The heat transfer between the freezer and refrigerating compartment is neglected and laminar air flow conditions were assumed. Simulation consequences demonstrate temperature stratification inside the refrigerating section cold and warm region were top and bottom respectively, in freezer compartment warm and cold region were top and bottom for each configurations. Comparison of temperature variation for numerous configurations of refrigerating compartment. The freezer and cold compartments is studied for three configurations. The perforated finned surface provides best result.
