气流横掠错列螺旋槽管束的传热及阻力特性的实验研究

Experimental Study on Heat Transfer and Draft Loss of Air Flowing Across Staggered Banks of Spirally Corrugated Tubes

本文根据强化传热试验台上取得的试验数据,整理出气流横掠错列螺旋槽管束的传热及阻力特性公式,为进一步研究开发强化换热产品及工业应用提供了试验依据。

Experiments have been performed to determine detailed average heat transfer characters of staggered tube banks in cross flow. The influence of H, P, S1, S2 on the heat transfer and pressure drop coefficients have been studied systematically and some formulae have been derived. These results may serve as experimental bases for further development of this product. spirally corrugated tube; staggered tube bank; Nusselt number; Euler number
