基于欧拉法模拟旋转帽罩水滴撞击特性
|
摘要
基于欧拉两相流理论,对旋转帽罩水滴撞击特性进行了数值模拟.通过引入耗散函数求解水滴相无黏欧拉方程,实现了欧拉法求解三维旋转帽罩的水滴撞击特性.分析了旋转帽罩转速对水滴撞击特性的影响.发现旋转帽罩转速越大,其表面水滴撞击极限稍有减小.在典型飞行条件与气象条件下,离心力对水滴运动轨迹的影响远小于惯性力对其的影响,旋转帽罩转速对水滴撞击特性影响较小.
Based on Eulerian theory,the droplet impingement characteristics of the spinner were simulated.The droplet impingement characteristics of the spinner were achieved by calculating the droplets' flow field with numerical diffusion.The rotate speed impact on the droplet impingement characteristics of spinner was analyzed.Results show that the greater the rotate speed,the smaller the droplet impingement limit.In typical flight conditions and weather conditions,the centrifugal force on the trajectory of droplets is much smaller than the inertial force.The rotate speed has little influence on the droplet impingement characteristics of the spinner.
