TL;DR: In this paper, the authors presented a simulation of multi-longitudinal vortices in a tube induced by triple and quadruple twisted tapes insertion, and the results verified the theory of the core flow heat transfer enhancement.

TL;DR: There should be a high possibility to enhance ZT in the SLMoS2-based materials as the thermal conductivity could be reduced largely by phonon engineering, and the predicted value of ZT is as high as 0.11 at 500 K.

TL;DR: In this paper, a three-dimensional turbulence analysis of heat transfer and fluid flow is performed by numerical simulation, and the simulation results show that the average overall heat transfer coefficients in circular plain tubes are enhanced with helical screw-tape of different widths by as much as 212-∼-351% at a constant tube-side temperature and the friction factor are enhanced by 33% to 1020%.

TL;DR: In this paper, an alternative hybrid membrane-based electricity generation system that operates as a heat engine is presented to convert low-grade heat into electricity, which consists of membrane distillation (MD), which absorbs thermal energy from the heat source and generates high concentrated salty stream, and reverse electrodialysis (RED), that converts the Gibbs free energy of mixing from the produced salty streams into electricity.

TL;DR: In this paper, two different methods, cold pressing sintering and loose powder Sintering, are adopted to fabricate the biporous nickel wicks for loop heat pipes (LHPs) in the present study, the porosity of the wicks is measured by Archimedes method and radius and distribution of pores is observed by Scanning Electronic Microscope.
