Summary: This research aims to investigate the axisymmetric flow and heat transfer of different shapes (Cylinder, Platelets, and Sphere) of Copper (Cu) nanoparticles on a radial stretching sheet. By transforming the energy and momentum partial differential equations into nonlinear ordinary differential equations and solving them with the BVP4C method, numerical solutions for the problem are obtained. The impacts of various shapes of Copper (Cu) nanoparticles and other parameters are thoroughly examined, including the solid volume fraction (/), Prandtl number Pr, unsteadiness parameter S, magnetic parameter M, slip parameter k, and Eckert number EC. The findings indicate that Platelet-shaped Copper (Cu) nanoparticles exhibit the highest flow performance, while Sphere-shaped particles have the maximum heat transfer rate.

Summary: Thermal non-Newtonian polymer coating flows are increasingly important in materials processing. This study investigates the laminar viscoplastic boundary layer flow and mixed convective heat transfer over a power-law nonlinear stretching surface. Mathematical models, including the hyperbolic Cattaneo-Christov heat flux model and Casson flow model, are used to simulate thermal relaxation effects and describe the non-Newtonian polymer characteristics. The resulting system of coupled nonlinear ordinary differential equations is solved numerically using the Chebyshev Spectral Newton Iterative scheme.

Summary: Metal foams with engineered local properties can enhance heat transfer in latent heat thermal energy storage (LHTES) units. However, the use of anisotropic metal foams for thermal energy storage has not been studied. This research mathematically modeled an anisotropic metal foam and simulated the phase transition behavior of a copper-coconut oil LHTES unit. The results showed that the anisotropic angle significantly affected the thermal energy storage power, and an optimum tilt angle of -45 or +45 along with zero anisotropic angle achieved the maximum charging power.

Summary: This research investigates the non-invasive hyperthermia therapy for abdominal aortic aneurysm (AAA), and analyzes the heat transfer and laminar flow in a heated AAA using an isothermal boundary condition. The study finds that reducing the viscous nature of blood in diseased vessels is recommended, as higher shear stress is observed for a higher index of the power-law fluid governing blood viscosity. Moreover, the study shows that the hyperthermia therapy becomes more effective when blood flows violently through the aortic, allowing for enhanced thermal energy transportation.

Summary: Latent heat thermal energy storage plays a key role in thermal management and renewable systems. However, the poor heat transfer characteristics of latent heat thermal energy storage units hinder their performance. Researchers have explored various heat transfer enhancement approaches, such as using nano additives, metal foams, and extended, wavy surfaces. This study investigates the impact of using wavy tubes in a composite phase change material and metal foam latent heat thermal energy storage unit, and explores the influence of different factors, including nanoparticle volumetric fraction, tube wave amplitude, tube wave number, and porosity coefficient, on the charging time, stored energy, and heat transfer behavior of the unit.

Summary: The paper investigates the forced fluid flow within a horizontal channel containing two semi-cylinders and two flexible baffles. The melting of phase change material, convective and conductive heat transfers, and fluid-structure interaction are considered. The influential parameters are dimensionless time, elasticity modulus of the baffles, and Reynolds number. The results show that increasing Reynolds number and decreasing elasticity modulus lead to a decrease and increase, respectively, in the melting volume fraction.

Summary: The impact of different foam shapes and configurations on the thermal energy storage rate was investigated for the first time in this study. A partial layer of metal foam was applied to enhance heat transfer in a channel-shaped latent heat thermal energy storage unit. The placement of the metal foam layer was varied to examine its effect on thermal energy storage power. The results demonstrated that changing the shape of the metal foam layer could significantly affect the storage power, with an approximately 60% variation observed for a fixed amount of metal foam. Therefore, careful selection of the metal foam layer's shape is crucial for design optimization.

Summary: The heat transfer during phase change in a heatsink filled with nano-enhanced phase change materials (NePCMs) was studied. The NePCM consisted of 1-Tetradecanol graphite nanoplatelets. The heatsink had an annular shape and experienced convective cooling on its outer surface and constant heat flux on its inner surface. The governing equations for momentum and heat transfer were solved using the finite element method. An artificial neural network (ANN) was used to establish the relationship between anisotropic angle, nanoparticle fractions, and melting volume fraction. The trained ANN showed high prediction accuracy and was used to generate melting fraction maps for design parameters. It was found that spreading the metal foam fins improved cooling performance without increasing weight, and nanoparticles had a negative effect on thermal energy storage capacity.
