Abstract: The influence of molecular (thermodynamic and transport) properties of air on gas-dynamic effects of pulsed-periodic energy supply in a transonic flow around airfoils is studied. Relations for air with allowance for excitation of vibrations and dissociation are taken as the thermal equation of state and the caloric equation. The influence of the transport properties (viscosity) is taken into account approximately, within the framework of the boundary layer model. It is demonstrated that the effects in qualitative considerations do not depend on taking into account the molecular properties, but the allowance for internal degrees of freedom yields a significantly lower temperature than the temperature predicted by the ideal gas model. Allowance for viscosity ensures certain attenuation of the energy supply effects.
Keywords: transonic flow, airfoil, molecular properties of air, aerodynamic characteristics, energy supply.
