Default Brownian Diffusion
Posts: n/a

1) Just wondering whether anyone has written UDF for Brownian diffusion force to account (for low Re flow)?

2) Compared to the default Brownian diffusion model (Li and Ahmadi (1993)), is there any better option?

3) How do I validate any Brownian diffusion type of model?
