The tab contains a toothed wheel which is driven at a high angular velocity by the impinging airstreams. 舵片上有一个带齿的轮,这个轮受到气流的冲击而高速转动。
If the fuel streams impinge with the airstreams directly at the exit of air-inlet, it makes negative effect on combustion efficiency. 燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高。
Biological treatment of contaminated airstreams is a technology which is an innovative method for control of air pollution. 生物除臭技术是一种较新的空气污染治理技术。
The model of viscous liquid annular jets is also promoted, namely, 3-D model of an annular liquid jet surrounded by swirling airstreams has been established. 将空心圆柱形粘性液体射流模型也作了推广,即建立了旋转气流中的空心圆柱射流分裂与雾化三维模型;
