| dc.description.abstract | In this document, we present a series of CFD simulations performed with starccm+V5 to build a sound proposal of windowless channel spallation target for ESS. The simulations increase progressively in complexity. The first simulation is a simple Mercury loop under the effect of a pulsed proton beam. The second one also includes a Hg/vacuum dynamic interface, using the VOF algorithm. The last simulations consider a LBE loop under vacuum subject to the thermal interaction with a proton beam, and is the basis for the proposal to ESS, still using the VOF algorithm. The simulation could be completed in a satisfactory way thanks to the use of a specific sharpening algorithm. This algorithm is explained and commented. The last simulations implementation is also described in details. The final results are shown. They appear very satisfying because the sharpening algorithm performs very well without giving rigidity to the free-surface and because the design elaborated seems a very promising basis for an ESS spallation target. | IT |
