A Numerical Analysis on the Natural Convect ion of the Square Channel inner from the Horizontal Plate with Protruding Heat Source

사각 채널 내에서 열원이 부착된 수평 평판에서 자연대류의 수치해석

The real chip and similarity model were used to investigate the thermal behavior and velocity distribution of air from the heat source with the location and the amount of heat experimentally and numerically, and compared. The heat generated in the block is not cooled by convection and show the high temperature by the stagnation of heat flow. After maintaining the high temperature of block by the natural convection, the sudden drop of temperature with the air flow was shown in the channel but the decreasing rate was small with the time. The inward block was effected by infinitesimal air flow generated between block and channel and outward block was effected by the entry condition.
