Abstract
To meet the requirements of real-time data processing and massive computation, it is necessary to introduce the parallel strategy into the System Thermal-Hydraulic part of System Program (STHSP) to increase computing speed. In this paper, an in-house parallel solver named STHSP-MPI was developed based on Message Passing Interface (MPI) method. Two-phase flow problems were solved by using the finite volume method and the Newton-Raphson algorithm. Firstly, validations of present parallel solver were performed quantitatively through several benchmark tests. Then, the computational efficiency was quantitatively described by speedup ratio and time overheads. Furthermore, the performances of parallel solver and program with adaptive mesh refinement were compared in detail. The simulation results show that the parallel strategy can significantly improve the computational performance of the system program while ensuring the accuracy.
