A free piston Stirling engine is a complex system that its transient behaviors of thermal
properties and dynamic characteristics are coupled with each other. In order to assess the …

The recuperation of otherwise lost waste heat provides a formidable way to decrease the
primary energy consumption of many technical systems. A possible route to achieve that …

This article introduces a novel averaging-based Lyapunov approach to design complex
oscillators such as free-piston Stirling engines (FPSEs). First, a class of thermal oscillators …

Stirling engines have a high potential to produce renewable energy due to their ability to use
a wide range of sustainable heat sources, such as concentrated solar thermal power and …

This paper presents a case study where steam at 1 MPa and 183 C (~ 140 psi/360 F) is
produced using very high temperature heat pumps (VHTHPs) at a pharmaceutical research …

This paper focuses on a neural network-based structure for predicting significant
unmeasurable parameters of a free-piston Stirling oscillator (FPSO). First, the nonlinear …

The global warming resulting from the emission of the greenhouse gases has led to
tightened restrictions on the use of fossil. Therefore, renewable energy for new energy …

Abstract The Free Piston Stirling Engine (FPSE) is a complex system, in which the transient
behaviors of its thermal and dynamic characteristics are coupled. To examine the strong …

Energy from waste heat recovery is receiving considerable attention due to the demand for
power systems that are less polluting. This has led to the investigation of external …

In this paper, the unique gas flow and heat transfer characteristics of an asymmetric
reciprocating hydrogen engine are investigated relative to a conventional engine. By means …
