Any recommendations on detail level on 3D model of bicycle wheel?
I am designing a velomobile for my master thesis and would like to do a CFD simulation of the wheels with and without wheel covers based on your "Flow Over a Rotating Wheel with Moving Ground" example.
I would like to simulate wheel with somewhat realistic spokes but I have read some recommendations that complex geometry does not work. I suspect that modelling the wheel correctly with crossed and touching spokes would not work so well.
So I plan on making a simple model using:
- radial spoke pattern (no crossing or touching)
- simple spoke cross section with no elbows or change of cross section (butted)
- no spoke nipples
Would that be a suitable level of complexity for Caedium, or could I easily stretch this by adding spoke nipples, butting or even crossed (real) spokes?
I have used Kt-Kl-omega on the velomobile body. Would that be a reasonable turbulence model for the wheel at 10 m/s velocity?
