Optimization results for axially variable metal felt regenerators in Stirling engines

This data set contains simulation results generated with the numerical simulation code kpsim <a href="https://doi.org/10.1016/j.applthermaleng.2016.09.176">[1]</a>, which was developed at the Laboratory of Thermodynamics of TU Dortmund University. It is a one-dimensional differential, so-called “third-order” model for regenerative gas cycles, which is organized in a modular way, so that almost any such cycle may be mapped by combining various components from a library. The cycle modelled within this contribution corresponds to Stirling-mode operation of a convertible experimental machine, which was also designed, realized and investigated at this laboratory <a href="https://doi.org/10.2514/1.B34726">[2]</a>. The numerical results are discussed in the related publication, which focuses on efficiency enhancements by regenerators with axially varying matrix structures in Stirling engines.
