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.
