Cluster of bubbles collapsing next to a wall exhibit interacting dynamics that are not predictable from the dynamics of single bubble collapse. We perform high resolution bubble cluster collapse simulations using a diffuse interface method to study the evolution of the pressure on the wall as a function of time and bubble parameters.
