Molecular kinetic analysis of a finite-time Carnot cycle
We study the efficiency at the maximal power ηmax of a finite-time Carnot cycle of a weakly interacting gas which we can regard as a nearly ideal gas. In several systems interacting with the hot and cold reservoirs of the temperatures Th and Tc, respectively, it is known that ηmax = 1− √ Tc/Th which is often called the Curzon-Ahlborn (CA) efficiency ηCA. For the first time numerical experiments...
متن کاملOnsager coefficients of a finite-time Carnot cycle.
We study a finite-time Carnot cycle of a weakly interacting gas which we can regard as a nearly ideal gas in the limit of T(h)-T(c) --> 0 where T(h) and T(c) are the temperatures of the hot and cold heat reservoirs, respectively. In this limit, we can assume that the cycle is working in the linear-response regime and can calculate the Onsager coefficients of this cycle analytically using the el...
متن کاملCarnot cycle at finite power: attainability of maximal efficiency.
We want to understand whether and to what extent the maximal (Carnot) efficiency for heat engines can be reached at a finite power. To this end we generalize the Carnot cycle so that it is not restricted to slow processes. We show that for realistic (i.e., not purposefully designed) engine-bath interactions, the work-optimal engine performing the generalized cycle close to the maximal efficienc...
