Optimizing thermodynamic trajectories using evolutionary and gradient-based reinforcement learning [PDF]

, 2019
Using a model heat engine, we show that neural network-based reinforcement learning can identify thermodynamic trajectories of maximal efficiency. We consider both gradient and gradient-free reinforcement learning.

Heat Transfer Intensification in Recuperative Heat Exchangers of the Stirling Engine

Engineering Proceedings
The non-stationary mode of movement of the working fluid flow in the Stirling engine causes serious difficulties in the design of heat exchangers. In most cases, the operation of conventional commercial heat exchangers is considered under steady-state ...

Comparison of the Net Work Output between Stirling and Ericsson Cycles

Energies, 2018
In this paper, we compare Stirling and Ericsson cycles to determine which engine produces greater net work output for various situations. Both cycles are for external heat engines that utilize regenerators, where the difference is the nature of the ...

Development of a theoretical decoupled Stirling cycle engine

Simulation Modelling Practice and Theory, 2011
Abstract The Stirling cycle engine is gaining increasing attention in the current energy market as a clean, quiet and versatile prime mover for use in such situations as solar thermal generation, micro-cogeneration and other micro-distributed generation situations. A theoretical Stirling cycle engine model is developed. Using a theoretical decoupled

Microscale Regenerative Heat Exchanger [PDF]

The device described herein is designed primarily for use as a regenerative heat exchanger in a miniature Stirling engine or Stirling-cycle heat pump. A regenerative heat exchanger (sometimes called, simply, a "regenerator" in the Stirling-engine art) is
