Abstract

Numerical simulation of flow through a Variable Mach number Flexible Nozzle (VMFN) at Mach 4 is carried out using the CFD code IMPRANS to validate the design of the nozzle based on the method of characteristics with boundary layer correction. The CFD analysis for the contour uses an implicit Reynolds-averaged Navier-Stokes (RANS) solver with Baldwin-Lomax turbulence model.Detailed flow characteristics like the centerline Mach number distribution and Mach contours of the steady flow through the converging x2013; diverging nozzle are obtained to study and assess the suitability of the design.
