“…Khandekar and Groll [11] clarified the role of gravity in the operation characteristics of a Closed Loop Pulsating Heat Pipe and its performance (i. e., overall thermal resistance) is strongly dependent on the flow pattern existing inside the tubes. The suitability of nanofluid in heat pipe applications was comprehensively reviewed by Brahim et al [12]. In their work, the recent developments have been reviewed.…”

In this paper, the experimental performance of a SS304 heat pipe under natural and forced convection modes using two different wick mesh sizes is reported. Deionised water was used as a working fluid with different heat inputs. The wick material is made up of SS303 with two mesh sizes (such as, 100 and 200 mesh). The heat pipe was positioned at three orientations (such as, horizontal, inclined, and vertical). During experiments, the ambient temperature was maintained at 30 ± 2 °C. The results showed that the heat pipe at an inclined position of 45° has about 71% higher heat transfer coefficient with minimum thermal resistance when compared to the horizontal and vertical positions. Moreover, the results confirmed that, the heat pipe using wick with 200 mesh specification at inclined position is an optimal configuration when compared to other configurations.

“…The heat transfer effect of nanofluids is the result of Brownian motion [4,5], solid-liquid interface properties [6], particle agglomeration [7] and many other factors. At present, researchers have done a lot of research on forced convection and heat transfer in nanofluid tubes, mainly including the influence of the types of nanoparticles, the proportion of particles in the total volume, the temperature of working medium, Re, heat flow density and other factors on the convective heat transfer coefficient and Nu [8][9][10][11][12][13].…”

Research on heat transfer characteristics of flow in tube of water-based nanofluids

et al. 2021

In this paper, the characteristics of forced convection heat transfer in water-based nanofluids are studied by means of experimental and theoretical analysis. Nusselt number of nanofluids were calculated by changing the volume fraction and the type of nanoparticles in the tube. The effects of Reynolds number and the volume fraction of nanoparticles on the forced convection heat transfer were studied. An exergy analytical model was established for the laminar heat transfer of nanofluid under the condition of constant heat flow. At the same Reynolds condition, the friction entropy production of the flow and heat transfer process in the tube increases with the addition of nanoparticles, and the heat transfer entropy production decreases at the same time. However, the magnitude of friction entropy production is only 10-6, which is negligible compared with the heat transfer entropy production. Therefore, in general, the loss of nanofluids is lower than that of pure water; for nanofluids, the exergy loss of hybrid nanofluid is lower than that of single nanofluid at the same volume fraction.
