DISPLAY
A simple case to demonstrate the effect of thermal
diffusion on the fields of H2 (in C1) and N2 (in C2).
The when the temperature gradients are positive, the
thermal diffusion acts against the bulk mass-flux and
acts to establish a negative gradient in H2 in the
cross-flow direction. When the temperature gradient
is reversed, the thermal diffusion acts with the bulk
mass-flux causing the overall values of H2 to be smaller
and a positive gradient to be established in the cross-
flow direction.
