摘要: |
研究锥形液膜在受限空间内的运动,该液膜由离心式喷嘴产生,并受到高速环形气流的冲击。根据空气动力学理论,建立了用于分析液膜运动规律的理论模型,提出了运动液膜的破碎准则和运动液膜破碎后形成的液滴平均直径的计算公式,计算结果可作为喷注器设计的参考依据。 |

Abstract: |
Movent of a conic liquid film in a restricted spase is studied in this paper. The film is produced by a centrifugal nozzle and impinged by high speed gas stream.Based on the theory of aerodynamics,some theoretical formulas for liquid film movement are established, a criterion of breaking up the moving liquid film is proposed and a formula for calculating the size of droplet formey by disintegration of the liquid film is presented. Calculation results can be used as a reference for atomizer design. |
