Optimization of Low Temperature Differential Stirling Engine Regenerator Design

Design of a 2.5kW Low Temperature Stirling Engine for Distributed Solar Thermal Generation

This paper focuses on the design of a Stirling engine for distributed solar thermal applications. In particular, we design for the low temperature differential that is attainable with distributed solar collectors and the low cost that is required to be competitive in this space. We will describe how these considerations drive the core design, the methodology for improving the design, and summar...

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...

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...

Multi-objective Optimization of Stirling Heat Engine Using Gray Wolf Optimization Algorithm (TECHNICAL NOTE)

The use of meta-heuristic optimization methods have become quite generic in the past two decades. This paper provides a theoretical investigation to find optimum design parameters of the Stirling heat engines using a recently presented nature-inspired method namely the gray wolf optimization (GWO). This algorithm is utilized for the maximization of the output power/thermal efficiency as well as...
