Simulation of Reacting Flows with a Portable Parallel Code Using Dynamic Load Balancing

摘要

The prediction of pollutant formation in turbulent flames requires a direct resolution of the Navier-Stokes equations using several hundred reactive species. The needed computer resources cannot be found any more on classical vector supercomputers. It is therefore necessary to write codes for parallel computers, which should offer in a near future a much higher computing power. But success can only be achieved if the difficult problems of portability and of load-balancing between the different nodes are taken into account. In this paper, we describe the development of such a parallel Navier-Stokes solver, and we show the first applications of this code concerning the investigation of flame structure.
