Mover guide in a linear electric generator with double‐sided stationary stators
The Journal of Engineering, Volume 2019, Issue 17, Page 3986-3990, June 2019., 2019 This study addresses double‐sided stationary stators in a linear electric generator with similar operation to a linear oscillatory motion electric machine. The plate mover in the linear electric generator's double‐sided stationary stators is powered by the acoustic power output of the thermoacoustic engine's acoustic line.

Modelling and Simulation in Engineering, Volume 2018, Issue 1, 2018., 2018 This paper describes a numerical model based on discontinuous Galerkin method for thermoacoustic investigation. Numerical investigation was conducted to study the behaviour of thermoacoustic wave propagations induced by thermal effects in 2‐dimensional enclosure. The compressible Navier‐Stokes equations are used as the governing equations.

Thermodynamics Performance Analysis of Solar Stirling Engines
International Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012 This paper provides numerical simulation and thermodynamic analysis of SOLO 161 Solar Stirling engine. Some imperfect working conditions, pistons′ dead volumes, and work losses are considered in the simulation process. Considering an imperfect regeneration, an isothermal model is developed to calculate heat transfer.
