As the velocity in the nozzle throat is sonic, the effect must be transmitted upstream through the boundary layer.
當噴管喉部達到音速時,這種影響一定是通過附面層向上傳播而引起的。 -
The calculation formulas for velocity coefficients 2 and 5 for the throat and throat inlet section were deduced from the theoretical research on the velocity coefficients in time - averaged basic equations by use of the unsteady momentum equation and time - averaged value calculation method
摘要運用非恆定的動量方程和時均值計算方法,對脈沖液體射流泵時均值基本方程中的流速系數進行了理論研究,推導出了喉管和喉管進口段流速系數2和5的計算式。
