摘要
对板翅式换热器平直翅片流道中流体流动与传热的性能进行了数值计算,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。
Fluid flow and heat transfer in plain - fin channels of plate - fin heat exchanger have been calculated in this paper. The average Nu and pressure drop curves of fluid with Re changing in seven different height, thickness and fin spacing channels have been presented respectively.
