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 ...

Optimization of Flywheel Rotor Energy and Stability Using Finite Element Modelling

open access: yesEnergies
An investigation on a flywheel is presented based on finite element modelling simulations for different geometries. The goal was to optimise the energy density (rotational energy-to-mass ratio) and, at the same time, the rotational energy of a flywheel ...
