Hello CFD Online community,

I'm a beginner in using SU2 for CFD simulations and I'm currently working on a project related to rocket nozzle erosion. I'm hoping to get some guidance on setting up the simulation and handling erosion modeling. Here's a bit more detail about my situation:

I'm attempting to simulate erosion patterns in a rocket nozzle using SU2. The rocket nozzle geometry is in STL format, and I've generated a mesh using Gmsh. My primary goal is to understand how particle impacts and thermal effects contribute to nozzle erosion.

1.How do I set up my configuration file in SU2 for a steady-state simulation considering particle erosion and thermal effects?

2.Are there any built-in models in SU2 for erosion, or do I need to implement custom code? Any resources or examples I can refer to?

3.How can I visualize erosion patterns and material loss in the nozzle after the simulation?

I've gone through the basic SU2 tutorials to get familiar with the software, and I've successfully run a simple flow simulation without erosion. However, I'm unsure about the additional steps required for handling erosion.

I really appreciate any help or pointers that you can provide. As a beginner, I'm eager to learn and apply these concepts to my project. Thank you in advance for your assistance!

Hi, welcome to the SU2 community!


We do not have a model for particle erosion, so you'll have to implement this yourself. What kind of erosion model do you need/have in mind? Does the erosion have an effect on the flow? If not, then you can implement a post-processing model (decoupled from the flow). You could do this in paraview, without diving into the su2 code. You could also implement some kind of Eulerian particle density field. You will need this as well if there is feedback to the flow solution (2-way coupling), for large volume fractions.

SU2 does not have a discrete particle model, so going into this direction might take too much time, unless you do a PhD and have time to spend 1 year on the implementation.

Hello,

Thank you for your response and insights. I've taken your advice into consideration, and I'm currently focusing on studying thermal erosion in the rocket nozzle using SU2.

Considering that thermal erosion is my primary focus and its impact on the flow is not significant in this case, I'd like to inquire about the steps involved in setting up a thermal corrosion simulation within the SU2 framework. Specifically, I'm interested in understanding how to properly configure the simulation to account for heat transfer and thermal effects in the nozzle.

If you could provide some guidance or point me to any resources related to setting up thermal corrosion simulations in SU2, I would greatly appreciate it. As a beginner, I'm eager to learn and make progress on this project.
