... effective pressure is theoretically the best engine for small capacity reciprocating heat engine. However, the practical Stirling engine performance is far from the ideal. As an alternative, practical heat engines based on thermodynamic cycles (without regeneration) other than the Stirling cycle have been...

... the transverse rocker beam as a low-friction way to transmit power from the pressurized envelope of a Stirling engine. Stirling engines have great potential for producing power from a wide range of energy sources including solar, renewables, and waste heat. CFD modeling could help in achieving that potential...

...Richard Kinnersly bioenergy conversion mathematical analysis computational fluid dynamics Stirling engines As the designer of the engine 1 featured in Dr. Mahkamov’s paper, 2 I welcome his pioneering application of CFD modeling to the Stirling cycle. The technique would have been...

... than a large stand-alone conversion plant. The current study proposes a small scale solid biomass powering system to explore the viability of direct coupling of an updraft fixed bed gasifier with a Stirling engine. The modified updraft fixed bed gasifier employs an embedded combustor inside...

...K. Mahkamov A prototype of a biomass Stirling engine was developed and manufactured by an industrial company prior to the numerical investigations described in this paper. Dimensions and performance of the prototype had originally been estimated using the company’s own simplified “first-order...
