摘要： The present invention relates to a transfer system of Stirling engines or stirling heat pumps that heats and cools the air before it enters the cylinder, and to its cooling or heating units. There is a two-way air path for inlet and outlet of the air between the cylinders as two-way system in the inventive heat transfer system. The air goes to the hot cylinder and heats the path, the air goes to the cold cylinder cools the path. The invention is particularly a two-way heat transfer system, it relates to allowing the use of large volumes of heating and cooling devices in a remote location from the Stirling engine. Thus, Stirling engines are suitable for the use of sources such as solar energy. It is possible to use devices such as Stirling pumps or engine radiators away from the engine by means of the inventive heat transfer system. And it becomes suitable for use in heating and cooling systems.

The mechanical system includes a plurality of components that includes a liquid piston heat engine. Couplings between the plurality of components are described. A plurality of layers for the mechanical system is defined. The mechanical system that includes the liquid piston heat engine is implemented. The implementation is across the plurality of layers. The implementation is based on the couplings between the plurality of components. The couplings are described using connectivity maps. The implementation is based on construction rules. An application programming interface is used to communicate information on the plurality of layers for the mechanical system. The plurality of layers provides progressive levels of abstraction for the mechanical system.

摘要： A thermoacoustic device (50) includes a process volume which is filled with a working fluid through which the acoustic wave propagates. The thermoacoustic device further includes an acoustic network comprising a tubular loop (6) configured with a passage (4) providing an opening in the loop and configured as acoustic circuit provided with a compliance volume (14), a thermo-acoustic core (8) and an inertance volume (16). Within the loop, the thermoacoustic core is at a first side (8a) thereof adjacent to the passage at a first path length through the loop, and at its second side (8b), opposite to the first side, the thermoacoustic core is at a second path length from the passage. The thermoacoustic device includes within the loop a spring-type partitioning element (20) that is configured to close off the cross- section of the tube and to be impermeable for the working fluid while allowing transmission of pressure waves in the working fluid through the spring-type partitioning element.

摘要： A device is disclosed herein which provides a domed cover of a combustion chamber enclosure applicable for use in Stirling Cycle engines, Ericsson Cycle engines, Rankine Cycle engines or other external combustion heat engine types which allows for the free flow of combustion air from the outer margins of the device toward the combustion air inlet in a vortexual fluid flow to achieve a more balanced stoichiometric ratio of the fuel/air mixture before ignition. This may be achieved by the employment of vanes to direct combustion air in a swirling vortexual flow as the combustion air enters the combustion chamber. Thermal barrier coatings and insulative materials may also be employed to minimize parasitic heat loss.
