Wind Tunnel Simulation Nvidia Flex

High I’m trying to simulate real-time airflow over an airfoil, but the particles are flying off instead of reattaching. See images.

Any help would be much appreciated

Cheers. I added a glass hollow box to contain the fluid to it can bounce off walls and particles compress each other. Results in images.
The more I reduce the emitter horizontal resolution (32x4 was used in image shown) the more frames I’m getting. Which is great for VR, but Flex doesn’t support instanced stereo rendering.

I’m trying to switch to flow to get that smokey visual, but complex collisions not working. Smoke passes through as can be seen in last 2 images. Any advice?
