摘要

本文研究了一种基于两相流建模的固体火箭发动机喷管的性能分析。采用欧拉-拉格朗日描述法计算了所设计的锥形喷管的单相和两相多维流动。流场计算结果用于计算推力，并通过与理想的一维喷管分析结果进行比较来评估喷管内的损失。进一步比较了单相流和两相流的计算结果。结果表明，颗粒对喷嘴效率有显著影响，对SRM喷嘴设计具有重要意义。

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.
