Invariant solutions of the thermal-diffusion equations for a binary mixture in the case of plane motion
I. I. Ryzhkov Institute of Computational Modeling, Siberian Division, Russian Academy of Sciences, Krasnoyarsk, 660036, Russia
Abstract:
The group properties of the thermal-diffusion equations for a binary mixture in plane flow are studied. Optimal systems of first-and second-order subalgebras are constructed for the admissible Lie operator algebra, which is infinite-dimensional. Examples of the exact invariant solutions are given, which are found by solving ordinary differential equations. Exact solutions are found that describe thermal diffusion in an inclined layer with a free boundary and in a vertical layer in the presence of longitudinal temperature and concentration gradients. The effect of the thermal-diffusion parameter on the flow regime is studied.
Keywords:
thermal diffusion, binary mixture, group analysis, invariant solutions.
