Surface injection using DPM CFD Simulation, ANSYS Fluent Tutorial


The discrete Phase Model is a method to simulate Multiphase flows.

A discrete phase model (DPM) is used when the aim is to investigate the behavior of the particles from a Lagrangian view and a discrete perspective, so it is more accurate compared to other models such as Mixture, Volume of Fluid and Eulerian- Eulerian, which investigate the behavior of the particles from Eulerian view; however, the calculation cost is much higher.

The geometry of the solution is a 3D cubic domain whose length in X and Y and the Z direction is 5cm, respectively. There is a square surface inlet on the cube’s left side with an edge size of 0.005m. Plus, Design Modeler software is used to create the geometry of the solution. ANSYS ICEM software is used for generating 92,809 Structured grids.

This CFD project is the 8th episode of the ANSYS Fluent General Training Course.

Methodology: Surface injection DPM

The simulation is transient, and the Pressure-based solver type is used due to the incompressibility of the working fluid. The gravitational acceleration effects are considered in the negative direction of the Y-axis. The Surface Injection type is used in the Discrete Phase Model (DPM) to model the particles.


At the end of the solution process, three-dimensional tracking of the injected particles is achieved. Also, their movement animation is recorded every five-time steps. As can be seen in the figures above, the particles are injected into the domain from the left side of the box.

The particles move a little down due to gravity, and the farther they go, the more they spread around until they exit from the right side of the domain.

Also, the injection summary is clear in the following figure, which shows the number of parcels, particles, and so on.
