...Mamta Devi; Urvashi Gupta The onset of binary/double-diffusive convection with conductivity and viscosity variations has been investigated for Casson nanofluids using Darcy–Brinkman model. Nanoparticle conductivity and viscosity are used as linear functions of volume fraction. The normal mode...

... outer square enclosure filled with nanofluid superposed porous-nanofluid layers. The Darcy–Brinkman model is applied for the saturated porous layer with nanofluid. Moreover, the transport equations (mass, momentum, and energy) are solved numerically using the Galerkin weighted residual method...
