TL;DR: In this article, the authors reviewed various configurations of VAWT along with their merits and demerits and found that coefficient of power for various configurations is different and can be optimized with reference to Tip Speed Ratio.

TL;DR: In this paper, a literature review focuses on the applications of Computational Fluid Dynamics (CFD) in the field of heat exchangers, and the quality of the solutions obtained from these simulations are largely within the acceptable range proving that CFD is an effective tool for predicting the behavior and performance of a wide variety of heat- exchangers.

TL;DR: In this paper, the effect of various combinations of tools and lubricants on the quality of the formed surface was studied by measuring the surface roughness with a surface rouness meter and examining the surface with a scanning electron microscope (SEM).

TL;DR: In this article, the effect of various material properties on the formability in SPIF has been investigated, and a new formability indicator was proposed to determine the sheet fracture in metal forming processes, where the degree of influence of a material property on the forming extent depends on the nature of the forming process employed.

TL;DR: In this paper, the properties of the prepared nanofluids were comprehensively characterised and analyzed by employing different techniques such as field emission scanning electron microscopy (FESEM), particle size analyser, Zetasizer, UV-vis spectrometry, rheometer, thermal conductivity meter and a pH measurement system.
