Abstract: Whole inner flow of Solid Fuel Ramjet(SFRJ)including mutation chamber, additional chamber and nozzle was numerically simulated by three dimensional implicit finite volume TVD scheme of N S/Euler equations Whole working process of subsonic, transonic and supersonic field was researched, which reveals the complicated fluid distribution of SFRJ Numerical results are very good agreement with experimental research

Key words: Solid fuel ramjet;Three dimensional flow;Flow field simulation;Numerical simulation

摘要： 利用三维隐式有限体积TVD格式求解NSEuler方程组,数值模拟固体燃料冲压发动机(SFRJ)突扩燃烧室、补燃室和喷管的统一内流场,研究了从亚声速到跨声速到超声速的整个工作过程,揭示了SFRJ内复杂的流场结构,并与试验进行对比研究,数值结果与试验吻合很好
