Heat flow and efficiency in a microscopic engine [PDF]

open access: yesThe European Physical Journal B, 2005
We study the energestics of a thermal motor driven by temperature differences, which consists of Brownian particles moving in a sawtooth potential with an external load where the viscous medium is alternately in contact with hot and cold heat reservoir. The motor can work as a heat engine or a refrigerator under different conditions.

Effect of Finite-Size Heat Source’s Heat Capacity on the Efficiency of Heat Engine [PDF]

open access: yesEntropy, 2020
Heat engines used to output useful work have important practical significance, which, in general, operate between heat baths of infinite size and constant temperature. In this paper, we study the efficiency of a heat engine operating between two finite-size heat sources with initial temperature difference.
