✦ Synopsis

A numerically fast algorithm has been developed to solve the viscous two-phase ¯ow in an axisymmetric rocket nozzle. A Eulerian±Eulerian approach is employed in the computation to couple the gas±particle ¯ow. Turbulence closure is achieved using a Baldwin±Lomax model. The numerical procedure employs a multistage time-stepping Runge±Kutta scheme in conjunction with a ®nite volume method and is made computationally fast for the axisymmetric nozzle. The present numerical scheme is applied to compute the ¯ow ®eld inside JPL and AGARD nozzles.
