A new multi-domain pseudospectral method is developed to simulate viscous compressible flow in a quasi-one-dimensional nozzle. The flow variables at the interface points are advanced in time using the same second-order time marching scheme as the interior points. The spatial derivatives of the inviscid flux vector are evaluated at the interface points using a spectrally accurate modification of Van Leer's flux vector splitting method. The derivatives of the viscous flux vector are evaluated alternately from neighboring sub-domains. The scheme is found to be spectrally accurate. Shock waves are resolved without oscillations for moderate Reynolds Numbers. 20 refs., 7 figs., 2 tabs.
