WebIn supersonic heat addition, the gas flow remains supersonic before, during, and after the heating process. The advanages of supersonic heat addition compared to subsonic heat addition are a lower static temperature and a lower static pressure for a given energy input. Two supersonic heat addition modes are available. WebThe main heat transfer mechanisms are convection, evaporation, radiation, heat capacity of the impinging spray, kinetic energy, aerodynamic heating, release of latent heat, and conduction heat transfer.
