用Excel修正流体阻力摩擦系数关联式的探讨

Research of modifying the connection equation on fricition factor of fluid resistence by Excel

本文应用Excel的函数库和图表向导功能,对莫狄图中完全湍流区域的摩擦系数的求取公式做一补充。即给出图中虚线的拟合公式。将此公式作为流体活动区域变换的判据,能够使计算机编程体系更加完备。

We will add on formula for fricition factor in fully turbulent region of Modi plans by features of Excel, as functions library and chart wizard. That is, we give a fitting formula for the dotted line in the plan. The formula can be as a criteria to judge which region fluid is flowing in. This does make computer programming system more perfect. Furthermore, this article has already made experimental discussion regarding this question that the fluid flow theory cannot differ between the turbulent region and the complete turbulent region accurarcly.
