I have produced trailing vortexes along the side of the 3D airfoil. Success! Backflow, however, still remains very small (roughly only 1 mm from the wall) or non-existent, depending on the...

I did a quick Solver analysis to guess the issues. The v-Mom and w-Mom residuals did not converge. Here are the locations of the maximum...

Replies: 9 Modeling Backflow for a 3D Airfoil (Wing of Finite Span) Views: 5,073 Posted By Josh Modeling Backflow for a 3D Airfoil (Wing of Finite Span) Hi everyone - The purpose of my current simulation is to demonstrate the backflow caused by the leading edge of a 3D airfoil. The backflow occurs along the side of the airfoil in the span-wise...
