Optimal performance of thermoelectric devices with small external irreversibility [PDF]

open access: yesarXiv
In the thermodynamic analysis of thermoelectric devices, typical irreversibilities are for the processes of finite-rate heat transfer and Joule heating. Approximate analyses often focus on either internal or external irreversibility, yielding well-known expressions for the efficiency at maximum power (EMP), such as the Curzon-Ahlborn value for ...

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.
