A porosity method to model the internal structures of a reactor vessel

Abstract

International audienceTo take into account the influence of a structure net among a fluid flow, without modelling exactly the structure shape, a concept of "equivalent porosity method" was developped. The structures are considered as solid pores inside the fluid. The method was studied for HCDA in LMFBR, but it can be applied to any problem involving fluid flow getting through a solid net
