Numerical simulation of rain ingestion characteristics of bifurcated intake

摘要

摘要:
使用数值模拟方法对一种带旁通道的分叉进气道进行不同雨水含量、不同来流速度下的吞雨特性开展研究。结果表明：吞雨总是使进气道流场畸变指数增加；在雨滴粒径均匀情况下，雨滴分离效率随雨滴粒径增加先减少后增加。雨滴粒径变化对流场总压恢复系数影响并不大，随着雨滴粒径增加，流场总压畸变指数先增后减；来流速度与流场中低速区共同影响雨滴运动轨迹。来流速度越大，旁通道排雨量越大，但主流道的吞雨量随着来流速度增加呈现出减少-增加-减少的趋势。

Abstract:
A bifurcated intake with a bypass channel was used to study the rainwater ingestion characteristics of different rainwater contents and different incoming velocities by means of numerical simulation method. The results showed that the rain ingestion increased the distortion index of the intake; the rain droplet separation efficiency decreased with the increase of the rain droplet particle size in the case of uniform rain droplet particle size. The effect of raindrop size change on the total pressure recovery coefficient of the flow field was not significant, with the increase of raindrop size, the total pressure distortion index of the flow field increased first and then decreased; the incoming velocity and the low velocity region in the flow field jointly affected the raindrop trajectories. The larger incoming velocity indicated the more rain discharged in the side channel, but the rain ingestion in the main channel showed a decreasing-increasing-decreasing trend with the increase of the incoming velocity.
