Project Description

In this project, numerical simulation of wind-driven rain has been done using Ansys Fluent software. The purpose of this project is to investigate the movement of raindrops in wind conditions of 5 meters per second, which has been done in two ways, one-way DPM and two-way DPM. The diameter of the drops is 0.5 cm but in order to be seen better, they have been scaled in contours and animation.


The two-dimensional geometry of this project has been produced with Spaceclaim software. The length of the computational area is 20 m and its height is 10 m.

Wind-Driven Rain

The meshing of this present model has been generated by Ansys Meshing software. The mesh grid is unstructured and the total cell number is 19741.

Wind-Driven Rain CFD Simulation

To simulate the present model, we consider several assumptions:

  • The solver is pressure-based.
  • The present simulation is unsteady in terms of time.
  • The gravity effect is equivalent to -9.81 m.s-1.

Here is a summary of the steps for defining the problem and its solution in the following table:

Viscous model Spalart Allmaras

particle treatment unsteady particle tracking

Wind-Driven Rain Results

According to the animation and speed and pressure counters, it is clear that solving this problem in the form of a one-way coupling was sufficient and there was no need to solve a two-way coupling. We know that in two-way couplings, the momentum effects of particles on the fluid are also calculated. Therefore, it has a much larger computational volume than one-way couplings, and in simulations where the number and size of particles are very large, these effects must be considered.

You can obtain Geometry & Mesh file and a comprehensive Training Movie which presents how to solve the problem and extract all desired results.
