Abstract
This document gathers some information on the free surface simulations with starccmV4.06 of preliminary versions of a CRS4 spallation target outsider candidate for the XT-ADS or FASTEF spallation target. The initial attempts are shortly illustrated and motivations for the changes are given. Once reasonably satisfied with the geometry, we test a rather simple condensation/sharpening algorithm on rather stiff operating conditions. Several variants, always based on a source/sink term for the light phase, are tested, systematically showing a degradation of the algorithm performances from the original algorithm. Finally, a full 3D loop of a potential candidate as spallation target with a sharp highly transient free-surface and a simplified thermal coupling is described and commented.
