Abstract

This paper describes future requirements for the computer exclusively oriented to the computational fluid dynamics (CFD) and the initiative at National Aerospace Laboratory (NAL,Japan). In order to promote CFD research activities, it is necessary to develop within the next two or three years a CFD-oriented computer, namely an ultra high-speed numerical wind tunnel (UHSNWT), whose CFD processing speed is more than 100 times higher than the currently used vector computer VP400, and also subsequently to develop a computer more than 1000 times faster by the end of the 1990`s. The requirements for the UHSNWT are discussed from a respect of development and operation costs, reliability, affinity with CFD programs, and operation environment. In addition, an NAL UHSNWT initiative is proposed based on the following; vector computer operational experiences, several software simulations, and future trend forecasts of LSI technology. It is concluded that developing the UHSNWT with a performance of more than 100 times higher than the VP400 is feasible using a parallel computer having a distributed memory and crossbar network. 12 refs., 8 figs., 7 tabs.
