Endoreversible Carnot machines with long-time reversible limit
Ramandeep S. Johal, Rajeshree Chakraborty
The well-known Curzon-Ahlborn (CA) engine [Am. J. Phys. {\bf 43}, 22 (1975)] runs in finite time and yields a finite power output. In order to recover the standard Carnot cycle fro…

Optimization of cooling power of a thermoelectric refrigerator: A unified approach
Rajeshree Chakraborty, Ramandeep S. Johal
We analyze the steady-state formalism for optimizing the cooling power of a thermoelectric refrigerator (TER), unifying the endoreversible and exoreversible approximations within o…

Optimal performance of thermoelectric devices with small external irreversibility
Rajeshree Chakraborty, Ramandeep S. Johal
In the thermodynamic analysis of thermoelectric devices, typical irreversibilities are for the processes of finite-rate heat transfer, heat leak and Joule heating. Approximate anal…
