gas diffusion to liquid
I am simulating a problem that involves species transfer from a gas bubble immersed in liquid phase flowing around it. What I know as my boundary condition at the bubble surface is the molar concentration of the species (that being oxygen) whereas in FLUENT, I can find the option of specifying only mass fraction of species. Does anyone know how to input the molar concentration of species at the bubble surface.
Thank You.
