“…Ahmed and Eslamian 11 studied laminar forced convection 60–62 of a nanofluid in a bottom heated rectangular microchannel. 56–58 The overall effect of the Brownian force created an oscillatory motion in place of a translational motion. On the other hand, for low Reynolds number, Brownian force created a slip velocity between the nanoparticles and the base fluid, which has resulted in a periodic velocity and temperature profiles.…”

“…Certain experimental results have been identified to be in a good agreement with macroscale theory, but in few instances large deviations have been observed in the results. Some investigations have depicted that the microchannel cross-sectional shape remarkably affect the flow behavior and the associated heat transfer ability of microchannels. A large number of investigations have employed microchannels with different geometries 25,36,50,53,54,56–59,61 apart from circular shape, 48,67 and further investigation is required to be done by taking different geometries of microchannels into consideration in order to achieve better designs for favorable results. It has been observed that both heat transfer and flow resistance are sensitive to the surface roughness of microchannels. It plays a constructive role on thermal characteristics and flow resistances under laminar flow. Furthermore, temperature computation is a basic method for observing heat transfer in microfluids.…”

The hydraulic and thermal characteristics of fluid flow in microchannels have advanced applications for the thermal management of electronic devices. There has been a wide development in the field of research concerning experimental procedures as well as numerical analysis of fluid flow in microchannels over the past decade. This article provides an overview of overall experimental and numerical studies in recent years to obtain clear understanding of various parameters affecting the fluid flow and heat transfer performance in microchannels. Furthermore, the article will come in handy for the researchers and scientists dealing with the basic correlations and some dimensionless parameters governing the hydrodynamic as well as thermic behavior of fluid flow in microchannels. This article underlines the recent studies on nanofluids in this specific area; additionally, it has encapsulated the influence on thermal performance by numerous designs of MCHS such as fins, ribs, etc. The latest research has revealed that there is a little agreement over the literature provided by experimental and theoretical analyses. Eventually, the conclusions drawn from this study and future prospective of research in this area have been thoroughly discussed.

“…A no-slip condition was defined for the adiabatic section. The coupled conditions were defined for the inner walls and The object of this study is to analyse the heat transfer characteristics in the thermodynamic cycle by CFD modeling, which is now widely used in solving heat and mass transfer problems [13][14][15][16]. Factors such as input heat flux, filling ratio and rotational speed are investigated.…”

Coolants are widely used to dissipate grinding heat in conventional grinding. This process, however, is not satisfactory as coolants often lose efficacy in grinding due to film boiling and can result in adverse health and environment effects. The present paper put forward the concept of a rotating heat pipe grinding wheel, attempting to reduce or eliminate the coolant amount and realize green machining. The heat transfer performance of rotating heat pipe grinding wheel was studied by using volume of fluid method in ANSYS/FLUENT. The influence of the input heat flux, filling ratio and rotational speed were investigated by a simulation method. Results show that the appropriate heat flux range for the rotating heat pipe grinding wheel was from 2000 to 100,000 W/m2, the ideal filling ratio was 50% and the rise of the rotational speed turned out to weaken the heat transfer coefficient. Finally, dry grinding experiments on Ti-6Al-4V were performed and the temperatures in both the rotating heat pipe and the grinding contact zone were monitored. The new designed rotating heat pipe grinding wheel showed a good prospect for application to green grinding of difficult-to-cut materials.

“…1. Liu et al [45] studied gas-liquid Taylor ow by taking into account the effects of several parameters on heat transfer enhancement. The authors discovered that while a higher wall heat ux improves heat transfer performance, a higher inlet temperature difference between gas and liquid reduces the Nusselt number (Nu).…”

The study is influenced by the significant progress made in the field of hydrodynamics and heat transfer enhancement of Taylor flow in vertical and horizontal pipelines. It maps the hydrodynamics and thermal properties of Taylor flow using 752 scientific articles published in refereed journals, extracted from the Web of Science Core Collection (WoSCC), using bibliometric analysis. The study identifies clusters that constitute the intellectual structure of the study domain, and investigates their linkages, by incorporating all citations from the Science Citation Index (SCI) from 2000–2021. The study highlights the most active, impactful, and influential parameters surrounding Taylor flow research. This analysis is critical for expanding our understanding of the intellectual network and identifying new research directions.
