Performance Analysis for Low-Temperature-Difference Stirling Engine

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...

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...

Performance Evaluation for a 100 W Stirling Engine

A small 100 W displacer-type Stirling engine, Ecoboy-SCM81 has being developed by a committee of the Japan Society of Mechanical Engineers. The engine contains unique features, including an expansion cylinder which is heated by either combustion gas or direct solar energy. Also, a simple cooling system rejects heat from the working gas. A displacer piston has both heating and cooling inner tube...
