Implementation strategies for real-time particle transport solver
Many problems in physics and engineering involve the transport of solid particles in a turbulent field. In some cases, it is desirable to study the transport of those particles in "real time". The prediction of erosion in the rotating part of hydraulic turbines is such a problem. This paper presents a semi-analytic predictor-corrector scheme adapted to the case of a rotating frame of reference. Simplification, related to the interpolation scheme required, is discussed as well as a parallel implementation using MPI on 10Base-T Ethernet interconnected workstations. The 3D solver is coupled with a high performance visualization software. Performance then shows a quasi-linear speedup. (C) 1999 Elsevier Science B.V. All rights reserved.
