Optomechanical Stirling heat engine driven by feedback-controlled light

Efficiency Bound of a Solar-driven Stirling Heat Engine System

A solar-driven Stirling engine is modelled as a combined system which consists of a solar collector and a Stirling engine. The performance of the system is investigated, based on the linearized heat loss model of the solar collector and the irreverisible cycle model of the Stirling engine affected by finite-rate heat transfer and regenerative losses. The maximum efficiency of the system and the...

A hot air driven thermoacoustic-Stirling engine

Heat engine driven by purely quantum information.

The key question of this Letter is whether work can be extracted from a heat engine by using purely quantum mechanical information. If the answer is yes, what is its mathematical formula? First, by using a bipartite memory we show that the work extractable from a heat engine is bounded not only by the free energy change and the sum of the entropy change of an individual memory but also by the c...

Performance Predictions and Test Results of a Free Piston Stirling Engine Driven Heat Pump

Recent progress on a Stirling engine driven hea t pump is described and a modeling technique for predicting engine dynamics is developed. The system described represents a very p romising configuration of engine driven heat pump, because o f the long life characteristics of the free-piston Stirling engin e and the hermetic nature of both the engine and refrigerant work ing fluids. Recent change...

Dynamic Behavior of a Free-Piston Stirling Engine Driven Heat Pump With Magnetic Coupling

A new low-cost design for a free-piston Stirling engi ne driven heat pump is presented. The new approach uses a linear-acting magnetic coupling to transfer engine power across a hermetic shell. Camp l i ance in the coupling affects the performance and stability of the system, especially with regard to matchin g the engine dynamics to the compressor load. This paper first describes test results ...
