Numerical solution of nonstationary problem for convection of binary mixture in horizontal layer

Nonstationary motion of a liquid binary mixture in narrow long horizontal channel with rigid walls heated according to certain law is considered. The possibility applying the Ostroumov-Birikh solution description flow under study used. It reduces problem solving mixed boundary value for system parabolic equations. A feature an additional integral condition on fluid rate. allows finding pressure gradient together functions velocity, temperature, and concentration. Applying constructed numerical procedure, analysis obtained characteristics carried out using water-ethanol as mixture. possibilities stabilizing unsteady controlling by means periodically changing thermal load wall are shown.
