Optimization of geometrical parameters for Stirling engines based on theoretical analysis
Cheng, Chin-Hsiang; Yang, Hang-Suin - In: Applied Energy 92 (2012) C, pp. 395-405
This study is aimed at theoretical analysis of the effects of the geometrical parameters on the shaft work of the Stirling engines. The optimal combination of the phase angle and the swept volume ratio, that leads to maximization of the shaft work of the engine, is obtained under different...

A high pressure and high frequency diaphragm engine: Comparison of measured results with thermoacoustic predictions
Steiner, Thomas W.; Archibald, Geoffrey D.S. - In: Applied Energy 114 (2014) C, pp. 709-716
A novel diaphragm Stirling/thermoacoustic engine has been developed and tested that operates at high pressure and high frequency thereby delivering good power density and efficiency. This engine does not require any high tolerance or exotic parts and may thus be amenable to low cost construction...

A mathematical model to develop a Scheffler-type solar concentrator coupled with a Stirling engine
Ruelas, José; Velázquez, Nicolás; Cerezo, Jesús - In: Applied Energy 101 (2013) C, pp. 253-260
This study develops and applies a new mathematical model for estimating the intercept factor of a Scheffler-type solar concentrator (STSC) based on the geometric and optical behaviour of the concentrator in Cartesian coordinates, and the incorporation of a thermal model of the receptor is...

Characterization of the power and efficiency of Stirling engine subsystems
García, D.; González, M.A.; Prieto, J.I.; Herrero, S.; … - In: Applied Energy 121 (2014) C, pp. 51-63
The development of systems based on Stirling machines is limited by the lack of data about the performance of the various subsystems that are located between the input and output power sections. The measurement of some of the variables used to characterise these internal subsystems presents...
