| Abstract: |
| The general computational software of rocket engine one dimensional nozzle nonequilibrium flow , which is based on one unite chemical library, can simulate the flow field of rocket engine nozzle with the propellants consisted of carbon, hydrogen, oxygen, nitrogen, fluorine, and chlorine elements. By computing the nozzle flow field with the propellant elements of hydrogen, oxygen and carbon, hydrogen, oxygen, nitrogen, the fields of velocity, temperature, pressure and all species mass fraction were gotten. They can be referenced by designer. |
