Enhancement of heat and mass transfer rates through various porous cavities for triple convective-diffusive free convection
TL;DR: In this paper, the authors examined the triple diffusive free convection in square, trapezoidal and triangular porous chambers under an impact of internal volumetric heat generation and found that the triangular cavity showed the highest heat and mass transfer rate.

Numerical study of the double diffusive convection phenomena in a closed cavity with internal CO2 point sources
TL;DR: In this paper, the authors analyzed the heat and mass transfer by natural convection in a square cavity with turbulent flow, covering a wide range of Rayleigh number of 104 −⩽−Ra ⩽ −1010 with a constant value of CH −= 3000 −ppm. Governing equations of mass, energy and concentration were solved by the finite volume method.
