Direct numerical simulation of Poiseuille-Rayleigh-Bénard flows in binary fluids with Soret effect
The Poiseuille-Rayleigh-Benard flows in binary fluids with the Soret effect were directly simulated by a mixed finite element method. A temperature perturbation was used as an initial disturbed source for the basic parallel flows. The whole spatio-temporal evolution of the binary fluid flows was exhibited. Initially only the disturbed mode with the wavenumber is amplified while others are damped, and continuously the amplified mode grows further and the nonlinear effect becomes important, after a nonlinear evolution transition the flow system evolves finally into a periodic right-going traveling wave.
