Title: Efficiency of finite-time heat engines:  from linear-irreversible 
to low-dissipation behavior

Abstract:

There is a great interest in understanding the optimal features  of the 
performance of finite-time thermal machines. Efficiency at
maximum power and the coefficient of performance at maximum cooling 
power, are some of the useful criteria that are studied.
Universal features of these quantities are observed in many different 
models, such as those based on endoreversibility
assumption, low-dissipation assumption, stochastic heat engines, and 
even quasi-static models. We discuss a model of heat engine
within the framework of linear irreversible thermodynamics.
The model runs in a finite cycle time. We show that the model can be 
mapped to a low-dissipation model whereby the entropy
generated in a heat-exchange step, is inversely proportional to the 
duration of the process. The optimal features of
the efficiency will be discussed.


Everyone interested is most welcome to attend!
