摘要： 根据国外实际发动机试车实测的喷管两相流中微粒直径等参数，用多参数最小二乘法拟合出较方便实用的质量加权平均直径Ｄ４３计算公式，以作为预估发动机性能的依据。
关键词: 喷管气流;二相流;粒度;拟合函数
Abstract: fitting formula for particle size D43 in solid rocket nozzle two-phase flow was developed by using multivariate least square method, which will be used as a criterion for prediction of solidrocket motor performances.
Key words: Nozzle gas flow;Two phase flow;Granularity;Fitting function
