Double-diffusive convection in a horizontal rotating porous medium layer saturated by a nanofluid, for the case when the base fluid of the nanofluid is itself a binary fluid such as salty water, is studied. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis, while the Brinkman model is used for the porous medium. The Rayleigh numbers’ for stationary and oscillatory convection have been obtained in terms of various non-dimensional parameters. Several results are obtained as limiting cases of the present study.
