We present a combined theoretical/computational framework to model jetting processes following shockwave/interface interactions. The model is based off treating the vorticity field as the principal independent variable. Following classical vortex dynamics, we develop a low dimensional set of ODEs which are easily integrated to simulate jetting processes. We identify basic mechanisms which enhance or suppress the jet speed. In a special case, we are able to identify an explicit and exact solution which completely suppress the jet growth. The results compare favorably with full hydrocode simulations.
Prospects for experiments and applications will be discussed.
