不同波纹通道综合性能的数值研究

Numerical Study on the Comprehensive Performance of the Different Wavy Channel

利用数值模拟的方法,研究了在不同雷诺数下,反向和同向排列的各种周期性充分发展的层流流动波纹通道的综合性能,分析了雷诺数和通道型式对流动及换热综合性能的影响。结果表明:各通道的性能随雷诺数的增大均呈先下降后上升的趋势;反向和同向时,各通道的综合性能有所不同。

In this paper, fully developed laminar compre- hensive performance is numerically studied for wavy channel with reversed and same direction arrangement. The influences of Reynolds number and the channels surface shape on the flow and heat transfer comprehensive performance are analyzed. The results show that the comprehensive properties of every channel first increased and then decreased when the Reynolds number increased, and the comprehensive performance of wavy channel with reversed ＆ same direction arrangement is different.
