A Semi-Empirical Equation for Estimating the Micro-Jet Ejection from Shocked Free-Surface

Based on the classical steady-jet theory and the equivalent linear mass assumption proposed by the author, a semi-empirical analytic equation for estimating the micro-jet ejection mass quantity from shocked free-surface with artificial wedged-grooves is developed in this paper. Comparing with a few practical examples, including experimental and two-dimensional numerical simulations, it shows the semi-empirical equation is relatively good for utilization in rough estimation.
