Supercomputing efforts on CFD for nonstationary flow analysis at NAL

Supercomputing efforts in computational fluid dynamics (CFD) are described. The environment supporting supercomputing is introduced with a brief historic retrospective on efforts to obtain supercomputation in the CFD discipline over the past decade. The present status of supercomputing efforts, including the graphics, is described. Results obtained from two studies typical of nonstationary flows are discussed. Finally, some requirements on future supercomputation and computers are noted from the author's personal point of view.<>
