The compression and expansion spaces of the Stirling engine are assumed to be isothermal and their volumes are assumed to vary sinusoidally. New expressions are deduced for the amplitude and phase of these variations. Using the expressions so deduced, these formula are derived for frictional losses inside the three heat exchangers (heater, regenerator and cooler), taking into account the variation in mass flow rate, fluid resistance, gas flow and shaft torque over the cycle, By comparing these expressions with the results of calculations using the quasi-steady flow model, it was found that confirmed coincide roughly with the low-temperature-difference Stirling engine.
