| 摘 要： | 研究了三角槽流道中过流截面的变化特性,求出了最小过流截面的计算式并确定了它的位置。指出当所研究的流动处于紊流流态时,一般文献在层流条件下推荐的计算公式不再适用了,可按本文方法计算三角槽的过流截面面积,确定雷诺数,选择流量系。

| Abstract: | The varying pattern of the sections along the triangle throttle is investigated,the formula for determination of the minimum area of channel sections is derived,and its position is also determined. It is pointed out that the formula recommended in some literatures for situations of laminar flow becomes disable under the turbulent regime where the sectional areas of the triangle throttle channel,Re number,and the coefficient of flow rate can be determined by using the formula presented in this paper. |
