abstract

In this paper, authors use the parallel calculation methods to solve the incompressible turbulent flow through a pump-turbine runner. The calculation aims at probing the road using parallel calculation methods to simulate complex flow field. The simulation is conducted based on the N-S equations, by using the k-ε model. SIMPLEC algorithm [1] is adopted in the numerical procedure with body-fitted coordination [2] and staggering grid system. The calculation is carried out on the THTF “Explore 108” Cluster Computer, where Solaris8.0 plays the roles of operating system and MPI1.2 as message-passing interface. The results of parallel simulation agree well with those of serial simulation, which shows that the parallel algorithms are feasible and useful to numerical simulation.
