| Research Abstract |
Aiming to the development of the Magneto-Hydro-Dynamics (MHD) high-Pr heat transfer database under the design conditions of the next advanced blanket in Fusion Reactors, we have succeeded the large-scale direct numerical simulations (DNS) of a MHD turbulent flows on both vector- and scalar types massively parallel processing supercomputer systems. The maximum computational speed was measured up 21 Tflops and the sufficiently parallelization efficiency by using up to over thousands CPUs was achieved, and the obtained DNS results were validated by means of spectral analysis.
