Abstract

The present study deals with double-diffusive convection within a two-dimensional inclined cavity filled with an air-CO2 binary gas mixture. The left and the right vertical walls are differentially heated and subjected to different locations of (CO2) contaminants to allow for the variation of the buoyancy strength (N). However, the horizontal walls are assumed adiabatic. The simulations are conducted using the finite volume method to solve the conservation equations of continuity, momentum, energy, and species transport. Good agreement with other numerical results in the literature is obtained. The effect of multiple parameters, namely, buoyancy ratio (N), thermal Rayleigh number (Ra), and inclination angle (α) on entropy generation rate is analyzed and discussed in the postprocessing stage, while considering both laminar and turbulent flow regimes. The computations reveal that these parameters considerably affect both the heat and mass transfer performances of the system.
