We present a thermodynamics experiment suitable for first year undergraduate students employing Stirling Engines to create demonstration of energy transformation and measure the mechanical efficiency such engines. Using an inexpensive transparent chambered Engine, can connect concepts as theoretical pressure-volume diagram with physical movements engine's pistons resultant useful output work sp...

A Stirling engine made of a colloidal particle in contact with a nonequilibrium bath is considered and analyzed with the tools of stochastic energetics. We model the bath by non Gaussian persistent noise acting on the colloidal particle. Depending on the chosen definition of an isothermal transformation in this nonequilibrium setting, we find that either the energetics of the engine parallels t...

The AASTINO (Automated Astrophysical Site Testing INternational Observatory) is a remote laboratory that has been operating at Dome C station on the Antarctic plateau since January 2003. It is designed to run throughout the Antarctic winter without intervention, and to collect data on the astronomical qualities of the site. A Stirling engine and a pair of solar panels power the observatory. Com...

Abstract We report on the study of student difficulties regarding a heat engine in context Stirling cycle by method measurement. An in-class test about with regenerator was taken three classes, and students were asked to perform one most basic activities—calculate efficiency engine. Our data indicate that quite few have not developed robust conceptual understanding engineering knowledge Notably...
