We present in this paper the numerical simulation of the full Navier-Stokes equation in vorticity-stream function form for the case of an inclined fluid layer with temperature modulation on the lower plate. The fluid flows on the plate which is inclined with some angle alfa with respect to the horizontal plane. The upper side of the viscous fluid layer is free surface.
Since we do not have constant temperature on the lower
plate, Rayleigh-Benard convection sets in immediately, for any value of Rayleigh number. We investigate the
stability of this convection for water as a working fluid. The results of direct numerical simulation are presented as fields of temperature, vorticty, stream function and velocity.
