The nonofluid convection driven by centrifugal forces in a rotating Hele-Shaw cell is studied by using a linear stability analysis. The nanofluid model used combines the effects of Brownian motion and thermophoresis. The linear stability equations are solved numerically to find the critical values of the Rayleigh and the wave numbers. The analysis reveals that the curvature parameter and the Eckman number delay the onset of convection, while the nanoparticle concentration Rayleigh number hasten the onset of convection.
