TALK=T;RUN(1,1) DISPLAY This simple case demonstrates the effects of thermal diffusion on a single light species, H2, diffusing in a heavy carrier species, N2. A source of H2 is placed near the outlet, and N2 flows in at the opposite end. Thermal (Soret) diffusion is the diffusion of species due to temperature gradients, and the model used here makes the light species diffuse more rapidly towards colder surfaces.
