EDWARDS' REFERENCE CYCLE FOR INTERNAL AND EXTERNAL COMBUSTION ENGINES
Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2014 Useful physical regularities of a reversible thermodynamic cycle for heat engines have been established in the paper. The engines are using fuel combustion products as a heat source, and the environment - as a heat sink that surpasses Carnot cycle ...

Dimensionality and geometry effects on a quantum carnot engine efficiency
Revista de Ciencias Tecnológicas, 2019 We calculate the efficiency of a quantum Carnot cycle for a particle confined in two different infinite potential wells, a cylindrical potential well of variable radius and a two-dimensional square potential well with a periodicity in one of it sides. We
