Abstract:
The aim of this paper is to propose a set of thermal models for the regenerator by taking into account the time dependent heat
transfer processes, and to combine them with the thermodynamic lumped description of the solar Stirling engine, accordingly to
recent description.
By using analytical and numerical methods, the optimum power of the engine is sought when various constrains (or not) are
considered, particularly fixed heat transfer rate available at the source.
A sensitivity analysis of the optimum power of the engine and the corresponding set of thermodynamics state variable with
respect to the main model parameters of the machine is performed.
The main conclusion of this work will reconsider the transient behavior of the regenerator heat exchanger for maximum power
output and corresponding optimum design of a solar Stirling engine.
