摘要
采用数值模拟的方法研究了板翅式换热器的流体流动与传热性能,得出了七种不同高度、厚度和翅片间距大小的翅片流道中流体平均Nu数和压力降随Re数变化的曲线。
The characteristics of fluid flow and heat transfer in plate-fin heat exchanger is studied by using the Numerical simulation method. The average Nusseh number and pressure drop curves of fluid with Reynolds number changing in channels with seven different of heights, thicknesses and fin spaces have been presented respectively.
