The 2-D MXene material has garnered immense attention in the multidisciplinary region due to its high surface area, excellent electrical conductivity, good biocompatibility, and tunable physicochemical properties. MXene nanoparticles can be utilized in thermal ablation to destroy unwanted tissues and tumors without invasive surgery. Therefore, this work investigates MXene (Ti3C2) embedded blood flow over a curved shape stretching artery. The mathematical model for hybrid blood flow is developed to see the thermal changes due to external pressure and diffusion. Furthermore, the flow model PDEs are equipped with Darcy-Forchheimer's condition, external magnetic force, thermal radiation, and heat source/sink. These PDEs are converted into a system of ODEs by a proper similarity conversion. The solution of governing equations are acquired numerically, the flow and thermal performance outputs are exhibited through pictorial and tabular representations. It is revealed that the thermal performance is enhanced due to sphere shaped MXene (Ti3C2) nanoparticles. The outcomes of this study can be utilized in photothermic therapy and other applications where heat transfer plays an essential role. [ABSTRACT FROM AUTHOR]

AbstractA numerical investigation is performed to scrutinize the enhanced thermal transmission of Carreau nanoliquid above an incessantly moving thin needle in the occurrence of nonuniform heat rise/fall effects. The arising system of nonlinear coupled equations is exercised numerically by employing a suitable numerical scheme, i.e. bvp5c Matlab solver. The prime motive of this research is to determine the effectual thermal conductivity of the nanoliquid by using Maxwell/Xue models to achieve enhanced energy transmission.

This article investigates the heat transmission rate in hybrid and tri-hybrid particles that emerged in Oldroyed-B blood flow flowing through wedge shape arteries. The rate type Oldroyd-B flow model is considered to examine the behavior of relaxation and retardation times. The transmuted nondimensional conditions and boundary restrictions are solved using the bvp5c technique. It is observed that the heat transmission rate is high for the tri-hybrid (GO-Al2O3-TiO2) blood flow combination compared to the hybrid (Al2O3-TiO2) blood combination. This study can deliver a vibrant opinion concerning heat transmission behavior and the blood flow nature in a wedge shape artery. [ABSTRACT FROM AUTHOR]

AbstractSolar energy is an essential source of clean, renewable energy that has the potential to transform our energy system and reduce impact on the environment. But, only 3.6% of solar energy is effectively used around the globe for electricity generation. So, using solar energy to the maximum extent is essential to control air pollution and save the environment for future generations. This article discusses the operative use of solar energy and suggests measures for optimal solar energy utilization in electric vehicles (EVs). The water-based silicon dioxide (SiO2) and aluminum oxide (Al2O3) combination is considered due to the high refractive index of SiO2 and scratch resistance and durability of Al2O3. A theoretical model was established by considering the shape of the solar collector, temperature change, nano spray, and radiative heat. The modeled problem was computationally resolved using the bvp5c MATLAB scheme, and simultaneous results were explored for various outlines of solar collectors. It is found that the shape of the solar collector and nanospray/nanocoating play a significant role in the practical usage of solar energy. Using curved-shaped solar collectors with water-SiO2-Al2O3 nanocoating allows the solar collector to absorb more light. This helps to improve the effectiveness of solar collectors in running EVs, which can reduce carbon growth. [ABSTRACT FROM AUTHOR]
