In a multi-cylinder type liquid piston Stirling engine (MCLPSE), columns in U-shaped tubes play the role of solid pistons mechanical engine. Besides straightforward structure, advantages MCLPSE are relatively low operation temperature difference below 100 K and use harmless working fluids air water. This study presents mass spring model for MCLPSE, from which we determine geometrical parameters...

Substitution of a metallic diaphragm for the power piston of a Stirling engine is shown to be a promising approach to transmitting power for a heat-actuated heat pump through a hermetic seal. Hydraulic fluid under high pressure transfers the power from the diaphragu to the compressor plunger, which is balanced by a counterweight. The discussion is divided into three parts which deal with the in...

The Stirling engine is an external combustion that can be utilized in electricity generation. Existing literature indicates air less expensive than helium as the working fluid but has low power and efficiency. Hence, present updated MATLAB code attempts to use a mixture of fluids or other mixtures gases. To this end, software proposes experimentally validated nonideal thermodynamic model for Ga...
