Discrete Particles in a Jet
Created using ANSYS 15.0
Learning Goals
In this tutorial, you will learn to:
- Initialize the case using a field function.
- Use Discrete Phase Model (DPM) to simulate particles in a flow.
- Define particle injection using an injection file / Create injection files using MATLAB codes.
- Visualize particle flow in CFD-Post.
Problem Specification
Consider a jet in a 1m * 1m region below. There are 400 particles randomly distributed in the region with random initial position as well as velocity direction and magnitude, as shown below.
As the particles are affected by the jet, they will have a tendency to travel along in the direction of the fluid flow. However, this property is governed by a non-dimensionalized parameter, the Stokes number. By simulating the movement of particles of different stokes number in a jet flow, the effects of the Stokes number on discrete particles in a fluid flow can be better studied and understood.
