Cumulative energy effect in the shock-discontinuity interaction under real-gas conditions

• A technique for improving ignition timing is investigated real-gas effects. Non-dissociating gas considered, with excited translational, rotational, vibrational, and electronic degrees of freedom. The relations are built on experimental data thus avoiding the complexity still offering satisfactory precision levels. main result: in real gases effect interaction can be stronger than that an ideal gas. Applied design efficient combustors hypersonic systems, detonation, space craft design, fusion research. recently proposed correction to model describing cumulative energy presence shock-discontinuity was done by re-considering Rankine–Hugoniot shock refraction equations. thermal equilibrium state, freedom considered. When applied N 2 at T = 3000 K, 11% density increase 17% temperature 7% pressure jump decrease were found, compared derived largely careful accounting all effects result findings interest shock-flame interaction, astrophysics,
