Hydrodynamic behavior of high power targets for future particle accelerators and, in particular, for the proposed Neutrino Factory and Muon Collider has been investigated via numerical simulations. The target will contain a series of mercury jet pulses of about 1 cm in diameter, interacting with strong proton pulses in 15 – 20 T magnetic fields. Simulations used the Lagrangian particle / smooth particle hydrodynamics code designed to accurately resolve free surface 3D hydrodynamic flows. Simulation results have been compared with existing experimental data and previous simulations performed with the Front tracking code FronTier. Both codes use realistic equations of state for mercury that support cavitation under critical tension. They are parallelized and optimized for the use on large distributed memory supercomputers. Simulations include the power range of neutrino factory (4MW, 8 GeV proton beam containing 150 bunches per second), the muon collider (the same power proton beam but delivered in 15 bunches per second), and proton beams exceeding the muon collider power range.
