TLDR
In this paper, a systematic thermodynamic approach is proposed that allows a rigorous formulation of the governing equations in non-isothermal situations, by introducing the surface effects in the energy and entropy balances.Abstract:
This contribution focuses on some non-classical aspects of capillary phenomena, mostly omitted in classical approaches, in particular the non-isothermal aspects. A systematic thermodynamic approach is proposed that allows a rigorous formulation of the governing equations in non-isothermal situations, by introducing the surface effects in the energy and entropy balances. The energetic quantities (work and heat) are calculated in a number of examples, such as adiabatic and isothermal wetting/dewetting of a porous medium, nanofluids heating, emulsion split, and new equilibrium criteria are derived were appropriate.read more

Critical review of heat transfer characteristics of nanofluids
TL;DR: In this paper, the authors summarize recent developments in research on the heat transfer characteristics of nanofluids for the purpose of suggesting some possible reasons why the suspended nanoparticles can enhance the heat-transfer of conventional fluids and to provide a guide line or perspective for future research.

Contact angles and their temperature dependence: thermodynamic status, measurement, interpretation and application
TL;DR: In this paper, the vertical plate model is used to measure contact angles on smooth and heterogeneous rolid surfaces and their temperature dependence. But the model is not suitable for smooth and homogeneous surfaces.
