Grouped random splashing droplets model for the rainfall distribution problem in flood discharge atomization
In this paper, a more accurate and efficient model is proposed for calculating rainfall distribution in flood discharge atomization. The random splashing droplets (RSD) model adopts Monte Carlo method to calculate, which requires a large number of droplets to be generated randomly, resulting in low computational efficiency. Based on the optimization method of particle motion calculation such as parcel particle and super droplet, a new grouped random splashing droplets (GRSD) model is established. The comparison between the analytical solution and the numerical solution shows that there is little difference in the calculation time between the two models under same number of droplets. As the number of droplets increases, the accuracy of both models increases, but the computational efficiency of GRSD model increases more obviously. Therefore, GRSD model has higher computational efficiency than RSD model with same accuracy.
