Numerical analysis of paraffin-wax/oxygen hybrid rocket engines
A predictive numerical approach, based on Reynolds-averaged Navier–Stokes simulations including the effects of turbulence, chemistry, fluid/surface interaction, and radiation, has been developed for paraffin-wax/oxygen hybrid rocket engines. A recently fired single-port paraffin-based hybrid rocket engine, with chamber pressures up to 19.1 bar, is taken as reference for the discussion of the results of the numerical simulations, which outline important features of the internal ballistics otherwise not observed in the experiments.
