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.
Also, particle 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.
