Summary: In this study, the melting phenomenon in a half horizontal cylinder cavity with rectangular heat sources was investigated using numerical lattice Boltzmann method. It was found that increasing the aspect ratio of the fins reduces melting time and increases liquid fraction, while higher Rayleigh number improves natural convection effect and melting rate. The highest melting rate was observed when two fins were positioned at 45 degrees with an aspect ratio of 7.5 at a Rayleigh number of 10^5.

Summary: This paper presents a numerical simulation of natural convection flow in annulus space with a partially heated inner cylinder. The study examines the effects of Rayleigh number and various cylinder ratios on Nusselt number, as well as velocity and thermal fields. The results show that Nusselt number increases with higher Rayleigh numbers and radius ratios. The fourth configuration, with heated zones on the left and right sides of the inner cylinder, offers better heat exchange under given conditions.

Summary: This article discusses the natural convection heat transfer of Ag/Al2O3-water hybrid in an enclosure with a rotating cylinder and an inner undulated porous layer under a uniform magnetic field. Various thermo-physical parameters are investigated, showing that an increase in Rayleigh number and Darcy number enhances heat transfer convection within the enclosure, while porosity has minimal impact. Rotation speed in a positive direction also has a favorable influence on heat transfer dispersion across the cavity.

Summary: The mixed convection of nanofluid within an inclined trapezoidal cavity in the presence of a magnetic field was explored using the lattice Boltzmann method. The study found that increasing the Rayleigh number and decreasing the Richardson number improves heat transfer. Increasing the volume fraction of nanoparticles leads to a higher average Nusselt number. However, increasing the Hartmann number reduces heat transfer. Altering the cavity's slope and the magnetic field's angle also has an effect on the flow and heat transfer. Applying a magnetic field has a more pronounced impact on heat conduction.

Summary: Both experimental and numerical studies show that nanoparticle suspensions enhance heat transfer for forced convection. However, there is diverse or contradictory conclusions regarding buoyancy-induced heat transfer in nanofluids. The study found that the hydrothermal behaviors of nanofluids strongly depend on the interaction between volume fraction and nanoparticle diameter, showing potential for improving heat transfer.

Summary: This study simulated the natural convection of water-Al2O3 nanofluid in a cold semi-annulus chamber with a hot block at the bottom, and applied an oblique magnetic field (MHD) to improve and control the flow. Increasing the volume fraction of nanoparticles was found to enhance the Nusselt number at low Rayleigh numbers, while the Nusselt number was inversely related to the Hartmann number at high Rayleigh numbers.

Summary: This paper investigates the effects of geometrical parameters, eccentricity, and perforated fins on natural convection heat transfer in a finned horizontal annulus using a three-dimensional lattice Boltzmann flux solver. The study found that increasing fin height and decreasing internal-cylindrical distance can enhance heat transfer rate, with negative fin eccentricity showing the most significant improvement compared to positive fin eccentricity. Perforated fins have a more significant impact at low fin spacing, while some enhancements are still observed at higher fin spacing.

Summary: The addition of a small amount of poly(ethylene oxide) (PEO) polymer to water droplets significantly changes the impact phenomena on superhydrophobic mesh surfaces and suppresses spray formation. The interaction between polymer chains and the superhydrophobic mesh surface leads to the suppression of droplet rebound and deposition of PEO droplets. Liquid penetration and formation of ligaments occur after a critical impact velocity and We number, but ligament instability and droplet detachment are observed under certain conditions.

Summary: This paper investigates the bouncing behavior of water droplets on superhydrophobic surfaces and finds a nonmonotonic relationship between the restitution coefficient and the Weber number. Droplet-surface friction limits the rebound height, and above a critical value, viscous friction dominates. Semiempirical formulas are proposed to describe the restitution coefficient, allowing for the prediction of successive rebounds.

Summary: Physic-Informed Neural Networks (PINN) have gained extensive attention for their ability to describe the physics behind problems without utilizing data-driven techniques, making them suitable for various complex physical and engineering problems. In this study, PINNs are applied to solve the Bratu equation from solid biofuel combustion theory by training a deep neural network to estimate the response with minimal error. The trained PINNs accurately estimate the answer to the problem and present the solution of governing BVPs systematically without prior knowledge of the answer.
