Abstract
This paper presents the application of a numerical method for gas dyna mics to model supersonic flows in a gas continuous, two-fluid medium. Specifically, flows in the two-phase medium are modeled only as single -phase compressible flow in a fixed, complex, multidimensional geometr y. Coupling effects involving liquid response to interfacial forces ar e neglected. The motivation for development stems from the desire to p redict blast interaction with liquid blankets in Inertial Confinement Fusion reactors. The model uses a second-order extension of Godunov's finite difference method to solve Euler's time-dependent equations of gas dynamics. The method uses a uniform Cartesian grid and a simple me thod for treating complex boundary geometries. The algorithm uses oper ator splitting to solve gas dynamics in multiple dimensions. Results o f several problems are qualitatively and quantitatively compared with previous work and experimental data.
