| 摘 要： | 由于非圆管道内非牛顿流体的研究日趋重要,使得作为比较基础的矩形管道内牛顿流的相应公式的正确作用变得迫切和频繁.而国内外许多重要文献所列有关公式包含有严重错误,笔者对此进行了罗列比较,给出了电子计算机逼近计算结果,并通过两个不同矩形截面管道的实验进行了验证和探索.

| Abstract: | Research of Non-Newtonian fluids in noncircular ducts becomes more andmore important.Being the base of comparison,the calculation of velocity and fric-tion coefficient for laminar flow in rectangular ducts are applied more frequently.But the formulas found in some famous textbooks and handbooks are not correct.The author points out these faults,gives the high-order approximate values withtypical aspect ratios,and investigates the relations between friction factor andReynold number with two different rectanguler ducts. |
