Spray CFD Simulation using Injection in DPM, ANSYS Fluent Training

The present problem studies Spray CFD Simulation using Injection in a Discrete Phase Model (the process of water spray into a cubic space) by ANSYS Fluent software. Spray CFD Simulation using Injection in Discrete Phase Model.

The present study aims to investigate water flow behavior during the spraying process from a tiny circular section to the inner space of a zone with a larger volume, which examines the behavior of water flow by tracing every particle. The simulation is time-dependent, and the solver is unsteady.

The geometry of this model consists of a rectangular cube zone with a circular cross-section as the input of the fluid flow on the upper wall of the domain. This geometry is drawn by Design Modeler software.

The model is then meshed by ANSYS Meshing software. The model mesh is unstructured, and 25,464 cells have been created.

Spray Methodology

Because particles must move discretely in a continuous medium, the Lagrangian perspective should be used to simulate this model. Therefore, a discrete phase model (DPM) is used in this modeling.

This approach means they must be tracked particle by particle in a continuous environment to analyze their behavior. So when using the DPM, an injection must be defined for the particles.

The material of the injected particles in the present model is water, and it enters the space from the inlet boundary of the model. The injection process is in the form of a surface, and the type of water particles is inert.

Spray Conclusion

After simulation, the 2D and 3D contours related to the velocity and mass concentration of the water particles are obtained in the last second of the simulation process.

Alsoparticle track related to spraying particles in 3D space is obtained based on the speed of spraying particles and the diameter of spraying particles.

The figures show that the injection of water particles is done correctly. These water particles are dispersed discretely from the upper inlet of the cube to the inside of the model and are distributed inside the model.

  1. Kyra Wisozk IV

    How does the simulation model the spray injection?

    • MR CFD Support

      The simulation uses the Discrete Phase Model (DPM) in ANSYS Fluent to model the spray injection. The DPM is used to track the trajectory of the discrete phase particles or droplets.

  2. Ransom Johns

    Hi, I wanted to make this product, and I had a question? Is the project’s unsteady resolved?

    • MR CFD Support

      Yes, this project is solved by applying a Transient solver. So, you can capture unsteady particle tracking.

  3. Shania Bashirian

    The MR-CFD is described efficiently.

  4. Mr. Loy Pacocha II

    This simulation is a fantastic tool for understanding complex flow dynamics!
