Summary: The worldwide scarcity of potable water has led researchers to search for alternative solutions. The solar still, which utilizes solar energy, is a device commonly used to desalinate saline water. However, its productivity is limited. The use of water-based nanofluids shows promise in enhancing the productivity of the solar still, as discussed in various literature.

Summary: This study investigates the heat transfer performance of multiwalled carbon nanotube nanoparticles dispersed in a binary mixture of water-EG in an automotive radiator. The results show that increasing the concentration of nanoparticles can improve heat transfer performance, but there is a significant decrease in performance at high nanofluid inlet temperatures. Moreover, the stability of the nanofluids is affected by aggregation and sedimentation.

Summary: An experimental study was conducted to investigate the heat transfer and flow characteristics of a heavy vehicle radiator using nanofluid. Deionized water mixed with anatase TiO2 nanoparticles was used as the nanofluid. Experiments were performed with different volume concentrations of TiO2 nanoparticles, inlet temperatures, and volume flow rates. The results showed that the highest heat transfer rate, heat transfer coefficient, and Nusselt number were observed at a volume concentration of 0.05%, an inlet temperature of 80 ?, and a volume flow rate of 11 LPM. The maximum enhancement in heat transfer rate, heat transfer coefficient, and Nusselt number compared to pure water were 22.2%, 48.2%, and 48.1% respectively. The performance coefficient was found to be above unity in the volume concentration range of 0.025-0.05% for each inlet temperature and flow rate.

Summary: Hybrid nanoliquids exhibit improved physical strength, mechanical resistance, thermal conductivity, and chemical stability compared to individual nanoliquids. The study found that hybrid nanofluids have the potential to significantly increase shear stress levels, up to 57% in some cases. Caution must be exercised in using these fluids, particularly in applications where control over shear stress is necessary.

Summary: The primary aim of this study is to examine the effect of squeezing hybrid nanofluids copper and magnetite with water flow across a horizontal surface under the impact of magnetic and radiative effects. The equations pertaining to momentum and energy are solved through a numerical approach. The results show that increasing the magnetic effect and volume fraction of nanoparticles strengthens the flow effect, while increasing the squeezing and permeable velocity parameter impedes the flow.

Summary: Sub-Sahara Africa, including Nigeria, faces serious issues with poor electricity supply. Generator sets, widely used in Nigeria, produce emissions harmful to the environment and human health. This study measured the concentrations of CO2, CO, and PM2.5 emitted from gasoline-powered household generators in Nigeria and found that the concentrations exceeded the recommended levels by the World Health Organization. The study recommends efficient generator use, fuel switching, stringent emission measures, and renewable energy as possible solutions.

Summary: This paper presents simulations of a cooling system for a battery pack consisting of lithium-ion plate batteries. The system includes six battery cells in two rows, placed in a channel with one inlet and two outlets. Transiently adjusting the cavity aspect ratio every 6000 s, the study calculates the PCM volume percentage surrounding each battery cell and the temperature of each cell for different values of the aspect ratio. FEM and COMSOL software were used for the simulations. The results show that the maximum temperature reduction occurs when the aspect ratio is changed, with a maximum reduction of 1.88 degrees C between AR2 and AR4 at 720 s. The effect of the aspect ratio on PCM volume fraction is maximal between 1260 and 3500 s.

Summary: This paper examines the irreversibility of natural and forced convection heat transfer of a nanofluid in a two-dimensional closed compartment, focusing on the significance of entropy production. The study considers insulation of the side walls, with the top and bottom walls being cold and hot respectively. The effects of the tilt angle of the closed compartment, the magnetic field's intensity, the Bejan number, and the Richardson number on entropy generation are analyzed using numerical simulations. The results indicate that entropy production decreases with increasing tilt angle up to 60 degrees, but further increase in angle leads to an increment in entropy production. The Hartmann number enhancement intensifies entropy production for strong forced convection, while it reduces entropy production for weak forced convection. An increase in Richardson number decreases entropy production.

Summary: This article simulates the free and forced convection in a two-dimensional rectangular enclosure. The study investigates the impact of parameters such as Richardson number (Ri) and Hartmann number (Ha) on the average Nusselt number (NUA). Numerical simulations using the Lattice Boltzmann method (LBM) and FORTRAN software are conducted. The results show that the increase in Ha enhances Nu at Ri=0.1, while for other Ri values, increasing Ha reduces NUA. The maximum NUA is achieved at Ha=40 and Ri=0.1, reaching 6.89. The orientation of the enclosure also affects NUA, with horizontal enclosure having the highest Nu (3.10) and vertical enclosure having the lowest NUA.

Summary: The study investigated the influence of concentration and temperature on the electrical conductivity, viscosity, and thermal conductivity of GNP/Fe2O3 hybrid nanofluids. Results showed that nanofluids exhibited superior electrical conductivity, viscosity, and thermal conductivity compared to water. The electrical conductivity and thermal conductivity increased linearly with concentration at a constant temperature, while the viscosity of the nanofluid increased with the addition of hybrid nanoparticles and decreased with temperature. Additionally, increasing the addition of hybrid nanoparticles in the base fluid enhanced the thermal conductivity of the nanofluid, and the thermal conductivity ratio increased with the addition of nanoparticles. These findings highlight the potential of GNP/Fe2O3 hybrid nanofluids for improving heat transfer and energy efficiency in various industrial applications.

Summary: A nonlinear state-space approach is used to model the microelectromechanical system of electrostatic energy harvesters. Analytical models of in-plane overlap, in-plane gap closing, and their compound structures are used to analyze the energy harvesting performance from heartbeats-generated vibrations. Comprehensive models of 1D, 2D, and 3D electrostatic energy harvesters are developed in state-space equation forms to simulate the performance under heartbeat excitation. This 3D feature significantly increases the power generation potential compared to individual in-plane overlap or in-plane gap-closing electrostatic harvesters.
