“…In addition, these materials have been used extensively in industrial applications, namely batteries, electronic devices, sensors, and as anti-corrosive additives due to their promising features like great mechanical and physicochemical attributes, low costs, and safety [19][20][21][22]. Since a thin lm of conducting polymers could preserve the substrate only for a short period, organic coatings and conducting polymer are usually combined to achieve effective and durable corrosion resistance [23][24][25]. Numerous studies have focused on examining the corrosive characteristics of PANI coatings proving that with the addition of nanoparticles (NPs) to the coatings, better anticorrosive properties will be gained due to the formation of the stable passive lm on the surface of the substrate.…”

This study comprehensively assesses the release rate of biocides, corrosion effects related to antifouling, and the physical properties of different paint types. Tests were conducted to measure thickness, viscosity, hardness, bending, adhesion, gloss, impact resistance, abrasion resistance, scratch resistance, polarization, and salt spray. The paints evaluated include resin-based, acrylic-based, epoxy-based, and vinyl-based formulations. The study investigates the influence of biocide content, biocide particle size, and immersion time on the release rate using a lab-scale setup. Results showed that acrylic-based paints had a higher biocide release rate due to faster hydrolysis, while smaller biocide particle sizes led to higher release rates in resin-based paints. Optimal total biocide contents were determined as 30% for acrylic-based, 60% for epoxy-based, and 50% for vinyl-based paints. Antifouling corrosion analysis demonstrated that the sample with the optimal release rate effectively prevents algae growth and fouling. Acrylic-based paint with 30 wt% biocide content exhibited superior adhesion with a dolly separation force of 4.12 MPa. Evaluating the impact of synthesized polyaniline on 30 wt% epoxy-based paint, a sample coated with 10 wt% polyaniline represented a low corrosion rate of 0.35 µm/year and a high impedance value of approximately 37000 Ohm.cm-2.

“…This interest stems from the remarkable attributes of nano additives, including outstanding thermal conductivity and enhancement of convective heat transfer. Additionally, these additives prevent dry-out, offer a substantial surface area, ensure stability, and enable customization of heat transfer characteristics [20][21][22][23][24][25][26][27][28][29][30]. Various nanosized materials have been incorporated into base uids to create high-heat transfer property nano uids.…”

This paper presents the outcomes of an experimental study employing flow visualization techniques to examine diverse flow patterns within closed-loop pulsating heat pipes (PHPs) utilizing Fe3O4/water as the working medium. A high-speed digital camera was employed to capture intricate flow patterns under various experimental conditions to gain a precise understanding of the operational mechanism of the PHP. The empirical findings demonstrated that in the evaporating segment of the PHP, the prominent flow pattern involved the oscillation of liquid slugs and vapor plugs, driven by the generation and expansion of bubbles through nucleate boiling. The results indicated a shift in the primary flow pattern of a closed-loop PHP employing Fe3O4/water. This transition progressed from a bubble flow accompanied by slug flow characteristics to an annular flow pattern. Additionally, the visualization study showed distinct flow patterns in the PHP’s evaporator, adiabatic, and condenser sections when Fe3O4/water was used with varying heat inputs. Notably, the oscillatory flow behavior of Fe3O4/water, the chosen working fluid, exhibited greater activity in comparison to water. This distinctive flow behavior contributed to achieving heightened thermal performance efficiency for the Fe3O4/water system, attributed to its faster attainment of the annular flow condition.

In this study, the heat transfer characteristics within the heat exchanger using water-based GO nanofluids were comprehensively assessed. An apparatus was constructed by scaling down an industrial heat exchanger. The nanofluid's thermal conductivity, specific heat capacity, viscosity, density, Prandtl number, and Nusselt number were examined at varying temperatures and GO nanoparticle concentrations. The results revealed that the thermal conductivity of the nanofluid increased with both temperature and nanoparticle concentration, reaching a peak value of 0.380 W m −1 K −1 at 85 °C and 0.1 wt %, leading to enhanced heat transfer rates through conduction and convection mechanisms. The specific heat capacity increased with temperature but decreased with higher GO nanoparticle contents with a maximum value of 3403.821 J kg −1 K −1 recorded at 40 °C and 0.01 wt %. The viscosity of the nanofluid increased with higher concentrations of GO nanoparticles, and the minimum value of 0.83 mPa s was observed at 85 °C and 0.01 wt %. The Prandtl number decreased with the temperature but increased with increasing GO nanoparticle concentration, suggesting a transition from convective to conductive heat transfer. A newly derived correlation equation for the Nusselt number, Nu = 0.0059(1 + 7.62ϕ 0.6886 )Pe 0.001 Re 0.9238 Pr 0.4 , allows predicting heat transfer enhancement in nanofluids. The findings emphasize the potential of nanofluids for improving heat exchanger performance and offer valuable insights into optimizing nanofluid applications in thermal systems.
