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.

Structural Stability of the Moore–Gibson–Thompson Heat Equation in a Semi‐Infinite Cylindrical Domain

Journal of Mathematics, Volume 2026, Issue 1, 2026.
This work analyzes the continuous dependence of solutions to the Moore–Gibson–Thompson (MGT) equation formulated via Green–Naghdi Type III second gradient elasticity theory. The governing system is defined on a semi‐infinite cylindrical domain, subject to homogeneous Dirichlet conditions on the lateral boundary.
