| 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 |
