    Impact of nanosized particles on hybrid nanofluid flow in porous medium with thermal slip condition
    (Taylor & Francis Inc, 2023) Rashid, Umair; Akguel, Ali; Lu, Dianchen
    A primary goal of this dissertation is to examine the magnetohydrodynamics (Al2O3 and Cu)/H2O hybrid nanofluid flow a porous medium with the nano-particles shape effect. The significant impact of thermal conductivity variation, slip condition and heat generation are also deliberated. The Spherical (Sphere) and non-Spherical (Lamina) types of Aluminum oxide (Al2O3) and Copper (Cu) nanoparticles are suspended in pure water (H2O) to form (Al2O3 and Cu)/H2O hybrid nanofluid. The modeled partial differential equations are transmuted into ordinary differential equations by using the similarity transformation technique. The converted ordinary differential equations (ODEs) are tackled analytically with the employing of well-known Homotopy analysis method (HAM). Also, the impacts of involving parameters on (Al2O3 and Cu)/H2O hybrid nanofluid velocity, temperature and Nusselt number are also taken into justification. A remarkable enhancement is noted the in non-Spherical (Lamina) shapes nanoparticles (Al2O3 and Cu) performance on temperature disturbance and heat transfer.

    Micropolar (copper-water) nanofluid flow past a stretching sheet with nanosized particles shape impact
    (Taylor & Francis Inc, 2024) Rashid, Umair; Ullah, Naeem; Akgul, Ali; Lu, Dianchen; Ul Rahman, Jamshaid
    Nanosized particles can be administered via distinct routes involving intraperitoneal and intravenous injection, pulmonary inhalation, and oral administration. Nanosized particles have been advanced as efficient target-specific strategies for the treatment of cancer, acting as agents and also acting as nanocarriers. Over the last few years, various kinds of nanosized particles have been developed based on several components involving silica oxides, nanocrystals, carbon, metal oxides, polymers, quantum dots, lipids, and dendrimers, together with enhancing a variety of newly developed materials. The focus of this study is to analyze the effect of dissimilar shapes of nano-sized particles on fluid flow past a stretching surface that is permeable. For this purpose, a micropolar nanofluid with a base fluid of water is considered. Both spherical (sphere) and nonspherical (lamina)-shaped nanoparticles of copper are used to study the enhancement of thermal conductivity. The highly complex governing partial differential equations of the problem are converted into ODEs via similarity transformations. The converted ODEs are tackled with the help of the homotopy analysis method. Our study shows that the performance of nonspherical(lamina) nanoparticles is better than spherical(sphere) nanoparticles in the disturbance of fluid motion, microrotation, and energy.
