| Abstract: |
| Numerical computation of velocity and turbulent intensity distributions are presented in this paper for the cold gas flow in a sudden enlarged combustion chamber of the liquid propellant rocket.The computational results are compared with the experimental data, and good agrrement is found.The method can be used as a reference of further design and research. |
| Key words: Liquid propellant rocket engine Combustion chamber Turbulent flow Numerical solution |
