This work is dedicated to study numerically an inclined solar distiller subject of a moving cold wall. The cavity is heated from left side and cooled from the right one. Constant and different concentrations are imposed in the two vertical sides of the cavity, while the other walls are adiabatic and impermeable. The flow is considered laminar and caused by the interaction of the thermal energy and the chemical species diffusions. Equations of concentration, energy and momentum are formulated using vector potential-vorticity formulations in its three-dimensional form, then discretized by the finite volumes method. The Rayleigh, Prandtl, Lewis numbers and buoyancy ratio are respectively fixed at Ra=105, Pr=0.7, Le=0.85 and N=0.85. Reynolds number (Re) is varied along the study from 0 to 150. The angles for the cavity inclination under this investigation are considered to be 0°, 30°, 45°, 60° and 90°. A particular interest to the flow structure and evolution of the heat and transfer i highlight in this paper.
