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. 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.

WebSep 27, 2010 · Benard Cells. When a fluid in a gravitational field is heated from below, it can develop a Rayleigh-Benard instability which causes the formation of convection cells as in the video above. The hexagonal shape of the cells is due to the boundary conditions of the fluid. It’s possible to form other shapes like spirals. The same mechanism drives ... WebNumerical simulations of thermal convection in rapidly rotating spherical fluid shells have been carried out with and without magnetic fields generated by the dynamo process. ... With increasing Rayleigh number the magnetic energy tends to saturate and the magnetic field assumes an increasingly filamentary structure.
