Thermodynamic Cycle of Stirling Engine without Regenerator with Pulsating Flow of the Working Body

The features of classical thermodynamic cycle of Stirling engine considering the periodic reciprocal motion of working body through the regenerator have been analyzed in this work. The possibility of satisfactory functioning of modified engine without regenerator with unidirectional pulsating motion of the working body in reсuperative heater and cooler has also been proved. The characteristic f...

Sensitivity analysis of dependency of working fluid thermo-dynamics properties to temperature on performance of Gama-type Stirling engine

This research proposes the effect of temperature variation in the Prandtl number on the power, the efficiency and the heat loss of the Gama-type Stirling engine. It should be noted that the Prandtl number included the viscosity, the thermal conductivity coefficient and the specific heat at constant pressures of the working fluid, which the temperature dependency of such first two thermo-dynamic...

Second Law Based Analysis of Fluid Flow in the Regenerator of Pulse Tube Refrigerators

As a necessary component, regenerator plays an important role in the refrigeration performance of the pulse tube refrigerator. The objective of this research is to investigate the flow characteristics in a porous regenerator of the pulse tube refrigerators, subjected to oscillating flow. The hydrodynamic and thermal behavior of the regenerator is investigated by considering porous media approac...

Numerical study on optimal Stirling engine regenerator matrix designs taking into account the effects of matrix temperature oscillations

A new regenerator matrix design that improves the efficiency of a Stirling engine has been developed in a numerical study of the existing SM5 Stirling engine. A new, detailed, one-dimensional Stirling engine model that delivers results in good agreement with experimental data was used for mapping the performance of the engine, for mapping the effects of regenerator matrix temperature oscillatio...
