| 内容記述 | In this study, the heat convection generated by a square-shaped heat source placed in a rotating fluid is investigated by numerical simulation. The incompressible Navier-Stokes equations with the Bousinesq approximation and the advection-diffusion equation for temperature are taken as the basic equations. The Coriolis force is added as an external force. These equations are solved by the fractional step method, and the nonlinear terms of the Navier-Stokes equations are approximated by the third-order upstream finite difference method so that calculations can be stably performed even at high Reynolds numbers. As a result, in some region of inflow velocity (Reynolds number), buoyancy (Grashof number), and Coriolis force (Rosby number), a stable periodic flow structure appears downstream of the heat source. Moreover, the parameter dependence of the flow and the mechanism of periodic structure generation are investigated. | |||||||||||
