本文沿用王补宜的处理方法,对宾汉型塑性流体在光滑圆管内作定常层流流动时的放热规律作了近似的理论分析,分别导得了t_w=常量和q_w=常量两种热边界条件下的放热系数的计算公式。并用实验数据及t_w=常量时的近似理论值作了检验和比较。
In this paper, we use the method of Wang-hui-yi to make an approximate theoretical analysis of the exothermic law of Bingham-type plastic fluid when it is used as a steady-state laminar flow in a smooth circular tube, which leads to two thermal boundary conditions: t_w = constant and q_w = The formula for calculating the exothermic coefficient. The experimental data and t_w = constant approximate theoretical value was tested and compared.
