Shock propagation in liquid-gas media
Abstract
In the present experimental and theoretical study of shock wave propagation in bubbled liquids, the third-order partial differential equation is used to analyze the behavior of semiinfinite-step or square pressure pulses, using the Laplace transformation to obtain solutions in closed form. Bubble gas species, liquids and pressure ratios are changed in order to observe their influences on bubble motion. The observed results are compared with theoretical predictions, taking account of liquid viscosity and nonlinear bubble oscillation under the influence of several different temporal pressure profiles. The influence of the bubble's exothermicity is observed, using stoichiometric and Ar-diluted oxyhydrogen mixtures, and compared to inert bubbles.
