Abstract
This paper presents an experimental investigation on the pool boiling heat transfer of water containing Al2O3 and TiO2 nanoparticles at 0.01%, 0.05%, 0.1%, 0.5% and 1% mass fractions at ambient pressure. A horizontal flat polished stainless steel plate was chosen as the boiling surface. Significant improvements in the boiling heat transfer coefficient and critical heat flux were recorded up to 0.1%. However, a decrease in heat transfer performance was observed at other concentrations. The surface wettability of nanofluids was improved as the static contact angle on the boiling surface decreased with an increase in mass fraction. The roughness of the boiling surface decreased due to the development of a layer of nanoparticles on it. Al2O3–water nanofluids showed better boiling performance than TiO2–water nanofluids. Finally, the present experimental outcomes are further compared and elucidated with the published reports and developed theories. This may be effective for a better understanding of pool boiling phenomena in nanofluids.

Abstract In this paper, we quantified the heat transfer coefficient (HTC) of Fe3O4 aqueous nano-suspension at various mass concentrations of 0.05% 0.2%. The potential role of operating parameters including heat flux perpendicular to the surface (HF), concentration of the nanoparticle (NP), strength of magnetic field (MF), zeta potential and concentration of a specific surfactant on HTC, critical heat flux (CHF) and transient fouling resistance of the surface was identified. Results showed that M...

Boiling heat transfer coefficient is one of the most efficient factors on the amount of transferred heat by boiling flow. New nanofluids have been extensively utilized for enhancing the performance of boiling process. Despite many experimental investigations around the pool boiling heat transfer coefficient of nanofluid, the precise mathematical scheme for the evaluation of this factor is of scarce up to now. The purpose of this research is prediction of heat transfer coefficient of Al2O3–water ...

Abstract A nanofluid, which is an aqueous fluid with nanoparticles, is an attractive medium for enhancing critical heat flux (CHF); however, its instability over a long period of time due to sedimentation and aggregation has impeded its successful application in industry. In this study, lightweight negatively charged TEMPO-oxidized cellulose nanofibers (CNFs) were utilized as a nano-sized substance in water and examined to enhance both the CHF performance and thermal stability of nanofluids. Owi...

Abstract Boiling heat transfer is widely used in energy power equipment, while the poor thermal property conventional fluids cannot meet the increase of heat transfer demand. The addition of nanoparticles into base fluids can modify the properties of base fluids and is a potential way to improve heat transfer characteristics. In present work, amorphous SiO2 nanoparticles with an average size of 98 nm were synthesized via Stober process. And they were added into water with different mass fraction...

In the present work, we focused on the thermal conductivity and viscosity of the synthesis as well as characterize metal oxide α-Al2O3 nanoparticles suspended in distilled water:ethylene glycol (60:40) ratio based stable colloidal nanofluid. The band gap of the α-Al2O3 with and without surfactant is 4.42 and 4.59 eV, respectively. The results show that nanoparticle with polyvinyl alcohol surfactant has smaller crystalline size (~23 nm) than without surfactant (~36 nm). The synthesized nanofluids...

Pool boiling of SiO2/water nanofluid over a copper flat plate heater at various inclinations of the heater surface was investigated experimentally. In this work, the effect of heater surface orientation on changes in surface roughness and on the characteristics of nanofluid boiling was studied. We examined pool boiling of silica nanofluid at various concentrations (<0.1 vol.%) and various heater orientations from a horizontal state (0°) to a vertical state (90°). The results showed that in nanof...

Abstract To investigate the effect of volume concentration and nanoparticle size on nanofluid boiling, a simulation with various concentrations of nanofluids and nanoparticle sizes was carried out using the HFP (heat flux partitioning) model with variations in the contact angle. The CHF (critical heat flux) of the nanofluid rose more than the base fluid. When the volume concentration was 0.025 vol% and the size of the Al2O3-nanoparticles was 50 nm, the maximum critical heat flux was 1515 kW/m2 a...

The benefits of nucleate pool boiling phenomena and their potential applications on thermal management of various microelectronic devices have triggered the development of new approaches that augment the magnitude of heat transfer rate. To implement these approaches, an accurate estimation of the boiling heat transfer coefficient between the fluid and the heated surface is often required. The acquisition of the boiling heat transfer coefficient must follow a better understanding of the bubble eb...

Pool boiling is a well-known heat transfer mechanism which is accomplished by submerging a heating surface in a pool of stationary liquid. The role and share of different energy transfer mechanisms in pool boiling can be determined through entropy generation analysis. In this paper, entropy generation due to energy transfer through circular surfaces is analyzed and the optimized thermodynamic system is achieved. Furthermore, two models of total heat flux (linear and nonlinear) are developed for ...
