Two-dimensional model for the two-phase flow simulation in a viking rocket engine combustion chamber
We have presented here a two-dimensional model for the two-phase flow simulation in a VIKING rocket engine combustion chamber. This model allows the transient flow description and shows the chamber unsteady response to combustion. Several calculations have been performed and the injection parameters influence on the flow pattern has been studied, as the concentration distribution of droplets, frequency and damping ratio of the oscillations. The numerical generation of undamped oscillations should enable us to a better understanding of this phenomenon. Therefore, numerical modellings of the main physical processes (e.g unsteady combustion) have to be improved. These problems are currently under development.
