Multigrid preconditioning of steam generator two-phase mixture balance equations in the Genepi software
Progress in Computational Fluid Dynamics, An International Journal
Within the framework of averaged two-phase mixture flow simulations of PWR Steam Generators (SG), this paper provides a geometric version of a pseudo-FMG FAS preconditioning of the balance equations used in the CEA Genepi code. The 3D steady-state flow is reached by a transient computation using a fractional step algorithm and a projection method. Our application is based on the PVM package. The difficulties of applying geometric FAS multigrid methods to the balance equations solver aredoi:10.1504/pcfd.2006.011319 fatcat:p4musqvo6fffje43menlqpzd4e
