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.

    How does the simulation model the spray injection?

      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.

    I found the descriptions of the DPM and how particles are tracked fascinating. Could you please clarify how the injection rate and particle size were determined in this simulation?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      In this simulation, the injection rate and particle size for the DPM are typically determined based on the specific requirements of the study, such as the characteristics of the physical spray system being modeled or experimental data. The values are inputted as parameters within ANSYS Fluent’s injection settings, tailored to accurately represent the behavior of the water spray in the virtual environment.

    I appreciate the detailed explanation of the simulation project. The use of DPM to model spray behavior seems extremely practical and useful. I am curious to know how well this model might scale for much larger or more complex spraying applications.

      Thank you for your positive feedback on our Spray CFD Simulation tutorial. While the simulation in this training was performed on a specific scale within a cubic space, the principles applied here using Discrete Phase Model (DPM) and particle injection techniques can indeed be scaled up for larger or more complex spraying applications. As the complexities and scale change, additional considerations such as increased computational resources, refined meshing strategies, and more computational time for accurately tracking a large number of particles might be necessary. However, the fundamental mechanisms of particle injection and behavior analysis remain applicable. If you plan to work on a larger scale project and need further assistance or if you have any specific requirements in mind, please let us know, and we will be glad to discuss potential approaches and solutions.

    I’m truly amazed by how realistically the spray simulation mimicked the actual spray dispersion. Was waviness or any perturbations in the particle path taken into account to emulate real-world behaviors of sprays?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      Thank you so much for your kind words! Regarding your question, in such simulations, certain complexities like waviness and perturbations can indeed be modeled to enhance realism. Perturbations can be introduced to replicate instabilities in the particle paths, thereby emulating real-world spray behavior. These phenomena are typically accounted for within the discrete phase modeling by adjusting initial conditions and interaction parameters to reflect real-world conditions accurately.

    What type of injection is applied for the water particles in the DPM simulation? And how does it affect the resulting spray behavior inside the cubic space?

    • Avatar Of Mr Cfd Support

      MR CFD Support

      The type of injection applied for water particles in the DPM simulation is a surface injection, where the particles are treated as inert. This setup allows for an accurate representation of the spray behavior as it replicates the discrete dispersion of water particles from the upper inlet, reflecting how they would move and spread within the cubic space.
