Effects of thermodiffusion on Darcy–Brinkman convection in a rotating binary nanofluid saturating a porous layer

In this study, the onset of convection in a rotating horizontal porous layer saturated by binary nanofluid was theoretically investigated under influence thermodiffusion and nanoparticles. To study convection, Darcy–Brinkman model employed for medium, thermal Rayleigh number derived analytically using linear stability analysis. Water–ammonia-based silver, copper, alumina, three nanofluids, were considered, effect nanoparticles on system analysed addition factor The Brinkman viscosity Bruggeman mean field approach conductivity used to impact Heat transport examined calculating heat transfer coefficient. effects nondimensional parameters involved nanofluids convective instabilities are depicted pictorially. dependence size cells is also discussed.
