A porosity method to describe the influence of internal structures on a fluid flow in case of fast dynamics problems

Modelling Pressurized Water Reactor cores in terms of porous media

“…Banerjee and Chan (1980) and Delhaye et al (1981) have established instantaneous space-averaged equations for a two-phase flow, and Robbe and Bliard (2002) have applied this method to a rod bundle. We use the same method as Robbe and Bliard (2002), but we introduce a different structure force.…”
