a webinar about cornering aerodynamics was scheduled not long ago. Unfortunately it was cancelled, so I decided to setup a cornering aerodynamics case in SimScale on my own. I have some questions regarding the setup of such a simulation because of some issues I face during the setup/post-processing process that prevent me from finalizing the case setup.
Here you can find the link to my project examining an FSAE nose design under cornering condition.
My approach on the setup of the case is to use a curved domain + MRF. The nose is rotating around a fixed point (0.765 9.125 0) outside of the domain at a constant angular velocity. The base mesh (region0) was defined as the cell zone. Some of the issues I’ve faced so far:
Defining the outlet boundary condition as “pressure outlet” results in a non converging simulation.
I’ve kinda fixed this issue by defing the outlet boundary condition as custom (Pressure inlet-outlet velocity at the outlet & Zero-Gradient at the rest of the boundary conditions.)
Given the fact that every single point has its own tangential velocity, what should the input of the k, omega initial conditions should be?
I’ve calculated the k, omega inputs based on the CoR of my model.
Based on the total pressure contour for the nose, it seems that the curvature of the flow was achieved. However, no wake is visible in post-processing. (u magnidude contour)
Maybe I’m missing something when it comes to post-processing the absolute velocity in SimScale?
I’ll update this post as I’m finding more issues.
Any tips so far? Feel free to ask any questions.
*Edit: Pressure inlet-outlet velocity at the outlet, not inlet.
