WebApr 14, 2024 · A model containing the main physical constituents is rather beneficial. This approach is given by the problem of rotating Rayleigh-Bénard convection (RRBC) : a rotating fluid layer heated from below and cooled from above. For large-scale systems, the governing parameters of RRBC take extreme values, leading to a regime of geostrophic turbulence. WebIn the present paper we have studied Rayleigh-Bénard convection in a nanofluid layer with vertical magnetic field heated from below and cooled from above. The model used for nanofluid includes the effects of Brownian motion and thermophoresis. The boundaries are considered to be rigid-rigid. The linear stability theory is employed and the resulting …

WebTransient natural convective heat transfer of liquid gallium, which has a Prandtl number of 0.023 at 310 K, from a heated horizontal circular cylinder to its coaxial triangular enclosure is studied numerically by employing the control volume method. Two orientations of the triangular cylinder are investigated and the Grashof number is varied from 10 4 to 10 7.
