文摘

We studied double-diffusive natural convection over circular cylinders in a non-Darcy porous enclosure with nanofluids using the finite volume method. The nanofluids on the outer enclosure walls and inner cylinders are passively controlled. We investigated the effects of the circular cylinders locations and sizes on the fluid characteristics. The effects of current physical parameters in heat and mass transfer and fluid flow have been studied with graphical illustrations.
