Natural Convection in an Air-Filled Cubical Enclosure with a Protruding Heat Sink: Application to a Thermoelectric Refrigerator

摘要

The present study evaluates the effects of a protruding heat sink located on one of the vertical walls of a cubic cavity, with a free convective laminar regimen. The best of three locations for the heat sink will be determined with the analysis of the velocity and temperature fields in the cavity. An optimal operation condition is required since the cavity will contain medical products with a specific temperature range. Three different locations for the heat sink, (in the +Y direction), are to be studied: (1/3)??, (1/2)?? and (2/3)??, where H is the height of the cavity, for different values of Rayleigh Number 10~3
