%X We consider a model for dusty gas flow that consists of the compressible Eulerequations for the gas coupled to a similar (but pressureless) system of equations for the mass,momentum, and energy of the dust. These sets of equations are coupled via drag terms and heattransfer. A high-resolution wave-propagation algorithm is used to solve the equations numerically.The one-dimensional algorithm is shown to give agreement with a shock tube test problem in theliterature. The two-dimensional algorithm has been applied to model explosive volcanic eruptions inwhich an axisymmetric jet of hot dusty gas is injected into the atmosphere and the expected behavioris observed at two different vent velocities. The methodology described here, with extensions tothree dimensions and adaptive mesh refinement, is being used for more detailed studies of volcanicjet processes.
