Hi all,
I am trying to calculate the concentration profile of two species with different diffusion coefficients in a narrow tube. The physics I'm using is " Transport of diluted species" for the default diffusion coefficient
(1e-9 m^2/s) the distribution is a symmetrical parabolic shape with pressure driven flow, but when i use (1e-11 m^2/s) for the second species the distribution is skewed. Does any one has any idea what's happening there?![]()
