文氏 管 内部 的 流动 与 传热较为 复杂， 不仅涉及喷淋液 滴与烟气在流动过程中的相互 作用，而且涉及喷淋液滴遇到高温烟气发生相变进行的传热传质。

The utility model relates to a preservation type water-jet vacuum pump which comprises a Venturi tube a sucking room and a jet .

本实用新型涉及一种防腐型水喷射真空泵，它包括 文丘里管、吸入室和 喷嘴。

Numerical simulation of the effect of venturi structure on the fluid flow during metal candle 's pulse jet cleaning

文氏 嘴结构对金属 滤管脉冲 反吹过程流动特性影响的数值模拟

It is well known that the jet flow loses its pressure at the throat when the high spees mixture of gas and water passes the throat of venturi duster because the pressure loss at the throat has direct ratio with the square speed of the jet flow .

文丘里除尘器的压力损失主要是高速气水混合射流通过喉管而造成的，通过喉管的压力损失与 射流速度的平方成正比。
