Hello,
What are the advantages and disadvantages of using these below turbulence models in simulating low Re (~ 0.2*10^5, around 10m/s) aerodynamics for Micro Air Vehicles?? 1. Spalart allmaras - Density based 2. K - w SST models - Pressure based Additional info: I'm only interested in prediction of aerodynamic coeff and stall characteristics.

Hi,
This is a very broad question. In my experience, if none of them deals with transition at low Re, neither of them will have advantages. The results will not be trusted. Reading a bit articles may help. Regards, Sheng |
