Revered flow for lower angles of attack range -- CFD Online Discussion Forums

May 22, 2022, 08:12	Revered flow for lower angles of attack range	#1
Ankit Kumawat New Member Ankit Kumawat Join Date: Dec 2021 Posts: 1 Rep Power: 0	I was performing simulations on NACA0003 airfoil at a Reynold number of 1e05 with the k-w SST turbulence model. The simulations are running perfectly fine for high angles of attack(>8 degrees) but it is showing a reversed flow for low angles of attack range. I have tried doing grid refinement as well but nothing worked. Any idea why is this happening? (Domain size: 10c both in the streamwise and crosswise direction; BC: Velocity inlet, Pressure outlet)
