The effect of heat conduction on the piston-in-cylinder dynamic pressure generator

摘要

This paper deals with the effect of heat conduction on the piston-in-cylinder dynamic pressure generator in order to indicate the transition from isothermal to adiabatic behaviour when increasing the pulsation frequencies. A mathematical model for the perfect gas in the cylindrical chamber is used to study the physical background of the effect of heat conduction on frequency characteristics of the pressure generator. Frequency characteristics of the pressure generator were theoretically obtained for different gases and average pressures.
