Performance analysis of a SRM nozzle-based on modeling of two-phase flow

This paper presents a study on performance analysis of a nozzle based on modeling of two-phase flow for an available solid rocket motor design. The single and two-phase multi-dimensional flow through the designed conical nozzle was calculated using an Eulerian-Lagrangian description. The flow field results are used to calculate thrust and to evaluate loses in the nozzle by comparing results with ideal one-dimensional nozzle analysis. Further comparison was made between single and two-phase flow computations. The comparison shows that the particulates have significant effects on the nozzle efficiency, hence play an important role for the SRM nozzle design.
