Stochastic Thermodynamics of a Particle in a Box

open access: yes, 2016
The piston system (particles in a box) is the simplest and paradigmatic model in traditional thermodynamics. However, the recently established framework of stochastic thermodynamics (ST) fails to apply to this model system due to the embedded singularity

A theoretical framework for the analysis of an opposed piston linear engine design

open access: yesResults in Engineering
Traditional crank-based engines face limitations due to mechanical, thermal, and combustion inefficiencies. In contrast, the opposed piston design of a linear engine generator mitigates frictional losses by eliminating rotational motion and crankshaft ...

Self-oscillations in an Alpha Stirling Engine: a bifurcation analysis

open access: yes, 2019
We study a thermo-mechanical system comprised of an alpha Stirling engine and a flywheel from the perspective of dynamical systems theory. Thermodynamics establish a static relation between the flywheel's angle and the forces exerted by the two power ...
