A computational study of the flow field characteristics and the performances of two-phase bubbly flow in water jet of a ramjet propulsion system with a diverging-converging nozzle has been performed. The analysis use a finite volume approach for the main flow coupled numerically with the Lagrangian equations for the bubbles motion including the change of bubbles radii with time. Computed results for an experimental two-phase flow in a ramjet propulsion system with a converging-diverging nozzle are presented to validate the numerical model. The performance of the ramjet for different initial velocities of the incoming water and for various locations of the bubbles injections has been studied. Results reveal that the best location for the bubbles injection is at the beginning of the nozzle section and produces a higher thrust.
