Gasdynamic Effects of Periodic Pulse Energy Supply in Widening Channel With Consideration of Air Real Properties
Keyword(s):
The impact of molecular (thermodynamic) gas properties on qualitative and quantitative characteristics of gasdynamic effects in a widening channel (with supersonic flow) at periodic pulse energy supply has been studied. As thermal equation of state and other gas thermodynamic properties equations for real gas have been used (with air parameters) with consideration of excitation of oscillation, dissociation and single ionization. We show that qualitatively the effects do not depend on taking molecular properties into account, but the existence of inner degrees of freedom leads to losses in tractive force of about 30 per cent for both periodic pulse and steady modes of energy supply.
