摘要
通过实验研究了低雷诺下,粗糙窄矩形管道中.肋间距对阻力系数和传热系数的影响规律,建立了预测平均阻力系数()和平均斯坦顿数()的方法,其结果可以应用在低流量散热器的设计中.
In this peper,an experimental study of fully developed turbulent air flow in rectangular channel of narrow aspect ratio with two opposite rib-roughed walls was performed to determine the effect of the rib pitch-to-height on friction factor and heat transfer coefficients with low Renolds number.A general Prediction method is given for average friction factor and average Stanton number in rectangular ducts.The result can be used in design of low flow radiator.
