The authors have carried out numerical simulations of the thermal hydraulic behavior of the LANL/IPPE/EDO-GP neutron spallation to be tested in LANSCE beam in year 2,000. The LANL/IPPE/EDO-GP target design, along with energy deposition provided by the Los Alamos meson Physics Facility (LAMPF) accelerator beam, has been analyzed with two commercial computational fluid dynamic (CFD) computer codes at Los Alamos. The LAMPF proton beam deposits energy in the target window diaphragm as well as the liquid metal coolant target. The computer codes were used to determine the maximum temperature in the spallation target diaphragm. The computational results from the two CFD codes are in general agreement and are consistent with the preliminary IPPE analysis. Limited studies were also performed to investigate ways to enhance cooling of the target by directing more flow through the center of the target. The goal of this latter part of the study is to provide guidance for the future design of a spallation target for the ATW project.
