In high-speed collisions of projectiles, pressure exerted by a resulting shock wave is so high that even solids begin to flow and hydrodynamics becomes relevant. Jetting results from hydrodynamic instability driving the evolution of an interface following shock loading. Our emphasis in this dissertation is mitigation of instabilities via several shocks and, specifically, the transfer of energy from a shock wave to another object. To that end, in 2022 and 2023 while on-site, we adapted Lawrence Livermore National Laboratory (LLNL) to explore the effects of shock front geometry on the transfer of energy during shock collisions via numerous computer simulations. The velocity of the ensuing jet was used as a representation for the energy transfer. Our results include, for the Richtmyer-Meshkov simulations, a new scaling law and a re-purposing of a previously derived shaped-charge formula. Good agreement was found between the scaling law and the simulation results. The shaped charge formula, however, failed to agree with the simulations.
