Description
Surface injection using DPM CFD Simulation, ANSYS Fluent Tutorial
Description
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.
Conclusion
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.

I recently completed the ‘Surface Injection using DPM CFD Simulation’ tutorial and I was fascinated by the particle tracking visualization. Is it possible to also track the temperature of the particles throughout the domain, and if so, how would that affect the simulation results?
MR CFD Support –
In the discrete phase model, it is indeed possible to track additional scalar properties of particles such as temperature. If enabled, you’d see how particle temperature changes as they interact with the continuous phase — the fluid temperature and possibly heat sources within the domain. This would require activating energy equations and appropriate heat transfer models. Particles could gain or lose heat, affecting their temperature and potentially the surrounding fluid’s temperature if heat exchange is significant — it may affect the buoyancy and the flow, providing more insight into the process being modeled.

Everything explained in the tutorial was clear, but I was wondering what kind of particles were used in the simulation and what properties they had?
MR CFD Support –
In the simulation for the DPM tutorial, the properties of the particles would typically be defined to match the characteristics of the real particles intended to be simulated. Possible properties include particle size, density, specific heat capacity, and material type. The exact specifications would be set in the ANSYS Fluent software to accurately reflect the behavior of the particles under study.

This Surface Injection DPM tutorial appears quite comprehensive. I’m particularly interested in analyzing how the particles behave when their properties vary, like their temperature or diameter. Does the tutorial offer guidance on assessing the impact of varying particle properties during the simulation?
MR CFD Support –
The tutorial indeed includes guidance on varying particle properties, such as temperature and diameter, within the Discrete Phase Model. You will learn how to adjust these parameters and analyze their impact using DPM in ANSYS Fluent.
