NEPTUNE_CFD High Parallel Computing Performances for Particle-Laden Reactive Flows
Résumé
This paper presents high performance computing of NEPTUNE_CFD V1.07@Tlse. NEPTUNE_CFD is an unstructured
parallelized code (MPI) using unsteady Eulerian multi-fluid approach for dilute and dense particle-laden reactive
flows. Three-dimensional numerical simulations of two test cases have been carried out. The first one, a uniform
granular shear flow exhibits an excellent scalability of NEPTUNE_CFD up to 1024 cores, and demonstrates the
good agreement between the parallel simulation results and the analytical solutions. Strong scaling and weak scaling
benchmarks have been performed. The second test case, a realistic dense fluidized bed shows the code computing
performances on an industrial geometry.
