The objective of the present work is the numerical and theoretical modeling of thermosolutal convection in an inclined cylindrical enclosure filled with a Casson fluid (binary fluid). The side walls of the enclosure are rigid, impermeable and adiabatic, and the horizontal walls are maintained at uniform temperature and concentration. Calculations are carried out for a variety of parameters related to our model, namely: the Casson fluid parameter (between 0.1 and 1), the Soret and Dufour numbers (between 0 and 1), the tilt number (between 0° and 90°), number of shoot ratio (between 1 and 2) and aspect ratio (between 2 and 3). The finite volume method was used for a spatial discretization of the system of equations obtained. Thus, we studied the effect of different parameters on the rate of heat transfer and concentration.
