PRESSURE DYNAMICS DURING SHOCK LOADING OF AQUEOUS FOAMS

The interaction of shock waves with aqueous foams has been numerically modeling on the basis of a gas-drop model. A modified Godunov scheme of second-order accuracy has been used to solve the gas-dynamics equat ions. The measured density distributions of the foam over height and t he results of calculational modeling of the foam structure were used a s starting data. The results of the pressure calculations are compared with experimental oscilloscope traces. (C) 1998 American Institute of Physics. [S1063-7842(98)00407-3].
