摘要: 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。

Abstract: With the method suggested by Wang Bu-xuan[4] an approximate theoretical analysis has been presented for steady laminar flow heat transfer of Bingham fluid through a circular tube. Equations have been derived for both boundary conditions, tw=constant and qw=constant. Numerical values of average Nusselt number have been calculated and compared with Hirais data[1,2] with good agreement.
