Description |
A parallelization methodology which incurs minimum modifications in a serial code for two-phase flows is presented here. The domain is mapped over a distributed-memory parallel architecture using unidirectional domain decomposition, with overlapping boundary control volumes that communicate using MPI. Five different 3-D transient test cases are taken for code validation and to study the parallel performance on 1, 2, 4, 8, and 16 processors. Parallel efficiencies ranging up to 99% are obtained. The property ratio of the fluids, their relative distribution over the domain, and phase-change solver module are found to influence parallel performance. Further, this study highlights the other bottlenecks encountered in parallel performance.
