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.
