throat velocity 中文意思是什麼

throat velocity 解釋
管喉流速
  • throat : n. 1. 【解剖學】咽喉,喉嚨;喉頭;頸前。2. 嗓子,嗓音。3. (器物的)咽喉狀部分;窄路,出入口。4. 【火箭】(噴管的)臨界截面。vt. 1. 用喉音說唱,沙啞地說唱。2. 掘(溝);開槽。
  • velocity : n. 1. 迅速;快速。2. 速度,速率。3. 周轉率。
  1. 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。
  2. 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。
