摘要
首次用组合坐标法对小空间自然对流换热问题进行数值模拟,并将封闭空间电缆群散热情况数值模拟的结果与实验结果比较,在所比较的工况点上,计算值与实验值相差小于5%。结果表明,组合坐标法在处理复杂封闭空间域的自然对流换热问题上,比起采用单一坐标具有更高精度。
The combination coordinates are used in the numerical simulation of natural convection heat transfer in a small space for the first time.The result of the numerical simulation of heat dissipation in a closed cavity is compared with the experiment result.The difference between the calculation value and the experiment value is less than 5%.As a consequence,the combination coordinates are proved to be more accurate than the single coordinate when they are applied to natural convection heat transfer in a comple...
