| 摘 要： | 为了简化电算程序,采用阿里特苏里公式作第一次计算,然后代入柯列布洺克公式,计算紊流过渡区的沿程阻力系数。既克服了后者的隐函数性质,又弥补了前者误差较大的缺点。另外,将上述计算延伸用于紊流的三个区,不需再判断流动处在哪一区,误差不大,简化了电算程序。

| Abstract: | In order to simplify the computer programme and to calculate the friction factor of transition zone in turbulent flow, the A. D. Aritshuri formula is adopted as the first step of calculation and then taken into th C. F. Colebrock formula. It not only overcomes the character of implicits function of the latter, but also remedies the shortcoming of larger errors of the former. In addition, it is extended to three zones of turbulent flow with less errors. So it is not necessary to decide in which zone the flow is and the computer programme is simplified. |
