Progress report on the simulation of the plunging jet configuration. EU projetc NURESIM Deliverable D2.1.3.1 (June 2006)

This progress report presents the preliminary work done for the numerical prediction of the plunging jet configuration. It consists in the definition of the most appropriate numerical configuration which should permit to obtain the most realistic behaviour of the gas below the free liquid surface. Several numerical domain (mesh and boundary conditions), numerical assumptions (steady state or transient calculations) and numerical models (mainly the effects of the non drag forces acting on the gas phase) have been tested. This report presents the most realistic numerical results and concludes on the most appropriate numerical domain and assumptions for the following tasks.
