“…5(a) to 5(d). The reduction in the thermal resistance is due to the formation of vapour bubbles at the liquid-solid interface (Harun et al 2019). The lowest thermal resistance is found at lower evacuation pressure 0.0799 bar which is 0.132243 K/W at 90W, 0.116598K/W at 80W, 0.131791K/W at 90W and 0.125142K/W at 60W for 30%, 50%,70% and 90% respectively.…”

“…Whereas some researchers found that a high concentration of nanoparticles improves thermal performance. Harun et al (2019) and Li et al (2020) reported that the heat transfer coefficient and thermal performance of PHP increase as the nanoparticle concentration increases in the nanofluid. Nine et al (2014) investigated the effect of different conc.…”

In this study, a closed-loop pulsating heat pipe experimental investigation was done with 1% wt concentration of cerium oxide/EG-water (60-40) nanofluid. The unsteady state measurement was done to determine the effect of heat input, filling ratio and evacuation pressure on the thermal performance of the closed-loop pulsating heat pipe. The thermal performance is assessed in terms of temperature variation, thermal resistance and effective thermal conductivity of the pulsating heat pipe. The most appropriate behaviour is observed at 0.0799 bar evacuation pressure with 50% FR. The lowermost thermal resistance of 0.116598K/W was observed at 0.0799 bar evacuation pressure and 50% FR. The effective thermal conductivity value was observed as 5078.34 W/mK at 50% FR, 0.0799 bar for 80W heat input which is 12 to 13 times better than pure copper. The pulsation action inside the pulsating heat pipe is verified with the power spectral density analysis. This study supports the better performance of the heat pipe at 50% FR with a lower evacuation pressure of 0.0799 bar.

Nanofluid had been widely used in heat transfer applications due to its better thermophysical properties. However, nanofluid had a problem in the stability of nanoparticles suspended in the based fluid. Several ways had been done to increase the stability of nanofluids including using surfactants. The purpose of this review is to uncover the stability and heat transfer performance of nanofluid using surfactants. A systematic review was used to collect the related articles for this review. This review shows the mechanism of two types of surfactants that had been used which are ionic and non-ionic. Furthermore, the stability of nanofluid is very important to enhance the thermal performance of nanofluid. The recommendations are highlighted to study the optimum amount of surfactant for respective nanofluids.
