Why do you select curvature correction?
One drawback of the eddy-viscosity models is that these models are insensitive to streamline curvature and system rotation, which play a significant role in many turbulent flows. A modification to the turbulence production term is available (as curvature correction) to sensitize the k-w SST model to the effects of streamline curvature and system rotation.
Detailed information about what terms are modified can be found in the ANSYS Help guide.
If you are unsure if it is required for your model, run a simulation with and without. Compare the results and make a judgement call.
Does that answer your question?
By the way, interesting bullet videos!!
Thank you for the reply. I will check out the ANSYS Help Guide. I do some automotive analysis and currently use the k-w SST but without curvature correction. I will run a case with both and compare. Thank you again for the reply and the videos on setting up an FSAE car was great. Wish it was around when I was learning Fluent!
No issues at all.
Thanks for the feedback, great to know the videos are helping people.
