-. WEAK SHOCK WAVES PROPAGATING IN FLUID-GAS S- MIXTURES

The structure of a weak normal shock wave is investiqated analytically for the one-dimensional flow of a fluid, containing gas bubbles. The relative motion of the gas bubbles and fluid are allowed for, and it is assumed that the gas bubbles follow a Stokes-drag law. It is shown that for large values of time the gas bubbles behave isothermally and the shock wave approaches a steady state. For maall values of time the gas bubbles behave isentropically-nd move faster than the fluid. Approved for Public Releas
