摘要
液滴在运动过程中与壁面发生碰撞后会发生破碎、反弹、附着等现象,这取决于液滴的尺寸、入射速度和角度,以及壁面的粗糙度、温度等因素.为了研究这个问题,在考虑以上因素的基础上,建立了液滴与壁面碰撞模型,并结合欧拉-拉格朗日两相流模型,分别对单液滴、水滴与壁面碰撞的情况进行了数值模拟.计算所得的结果与预期相同,并且与试验结果也吻合得较好,从而证明了所使用的液滴与壁面碰撞模型的正确性和合理性.
After droplets collide with a wall, they either break up, rebound, or adhesion occurs. The result depends on droplet size, incident velocity and angle, wall roughness, temperature, and so on. To study this problem, after considering the above factors, a droplet-wall collision model was constructed. Combined with the Euler-Lagrange two-phase model, the mechanics of collisions between single droplets, multiple droplets and walls were simulated. The computational results were as expected and in good agreement with experimental results, which shows the accuracy and reasonableness of the model used.
