Parallel computation and visualization of three-dimensional, time-dependent, thermal convective flows

چکیده
A high-resolution numerical study on parallel systems is reported on threedimensional, time-dependent, thermal convective flows. Numerical results are obtained for Rayleigh numbers up to 5 x 107 and for a Prandtl number 0.733 equivalent to that of air, in a cubical enclosure, which is heated differentially at two vertical side walls. A parallel implementation of the finite volume method with a multigrid scheme is discussed, and a parallel visualization system is developed on distributed systems for visualizing the flow. The details of the three-dimensional, time-dependent flow are described. Separations of the flow near the horizontal walls occur at R = 107, and y-variations of the flows are getting stronger with the increases of Rayleigh number.
