    (Nature Portfolio, 2024) Imran, Muhammad; Basit, Muhammad Abdul; Yasmin, Sumeira; Khan, Shan Ali; Elagan, S. K.; Akguel, Ali; Hassan, Ahmed M.
    Nanofluids become significant in the mass and heat transfer models, especially in engineering problems. Current proceedings focused on the bioconvective Maxwell nanofluid flow passing through the permeable stretchable sheet contingent to nield boundary conditions involving effects of activation energy and thermal radiation. Various physical quantities are involved in this mechanism like magnetic field, thermophoresis, and Brownian motion. The main objective of the study is to report the heat and mass transport in the existence of motile microorganisms. In a mathematical perspective, this structured physical model is going to govern with the help of partial differential equations (PDEs). These governing PDEs are then converted into dimensionless ordinary differential equations form by utilizing appropriate similarity transformations. For numerical results, the shooting technique with 'bvp4c' built-in package of MATLAB was implemented. Computed results are then visualized graphically and discussed effects of involving physical variables on the nano-fluid flow profiles are comprehensively. From results, it has been concluded that the fluid flow velocity, temperature, concentration, and microorganism density profiles show escalation on increasing the numeric values of porosity, thermophoresis, buoyancy ratio, bioconvection Rayleigh, Peclet number parameters and decrement reported due to increasing the counts of Prandtl number, magnetic field, radiation, Brownian motion, Lewis number as evident from figures. The numerical outcomes observed by fixing the physical parameters as 0.1 < lambda < 3.0, 0.1 < M < 1.5, 0.1 < Nr < 6.0, 0.1 < Rb < 1.5, 0.1 < Nb < 6.0, 0.1 < Nt < 1.0, 2.0 < Pr < 2.9, 0.1 < Rd < 0.4 . Magnetic field and Brownian motion create retardation impact due to the liquid momentum. In tables, the numerical values of Skin friction, Nusselt number, Sherwood number, and microorganisms density number are presented and also comparison table of our computed results and already published results is included for the validation.

    Comprehensive investigations of (Au-Ag/Blood and Cu-Fe3O4/Blood) hybrid nanofluid over two rotating disks: Numerical and computational approach
    (Elsevier, 2023) Basit, Muhammad Abdul; Farooq, Umar; Imran, Muhammad; Fatima, Nahid; Alhushaybari, Abdullah; Noreen, Sobia; Eldin, Sayed M.
    The purpose of this work is to investigate the Darcy-Forchheimer flow of a hybrid nano -fluid within two parallel discs. We combine gold Au, silver Ag, copper Cu, and iron oxide Fe3O4 nanoparticles with base fluid blood in this framework. An appropriate similarity variables tech-nique is implemented to transform partial differential systems into ordinary systems. In the results validation section, the numerical result is evaluated using a higher-order precise algorithm (bvp4c), and determined to the analytical result is by making use of the firing approach. Pictorial judgments revealed the estimates of several physical variables that arise over the momentum distribution and thermal distribution profiles. As compared to nanofluid, hybrid nanofluid significantly improves heat transfer rate. The thermal profile is improved when the Brinkman number increases in value. As the porosity parameter is increased, the velocity profile decreases. As the amplitude of the rota-tion parameter increases, so does the pressure profile. The Darcy-Forchheimer medium investiga-tion of a hybrid nano-fluid streaming through the middle of two parallel disks is addressed, taking into account viscous dissipation and heat radiation for various nanoparticles. Additionally, enough agreement is observed when the numerical findings are compared to previously reported and analytical data. As compared to simple nanofluids, hybrid nanofluids have shown higher ther-mal properties and stability, making them attractive candidates for thermal applications such as solar thermal systems, automotive cooling systems, heat sinks, engineering, medical fields, or ther-mal energy storage.(c) 2023 THE AUTHORS.

    Mathematical analysis of heat and mass transfer efficiency of bioconvective Casson nanofluid flow through conical gap among the rotating surfaces under the influences of thermal radiation and activation energy
    (Elsevier B.V., 2024) Basit, Muhammad Abdul; Imran, Muhammad; Akgül, Ali; Khan Hassani, Murad; Alhushaybari, Abdullah
    In the current proceeding, the flow of incompressible non-Newtonian nanofluid called Casson nanofluid is considered. A conical gap occurred among the rotating disc and the cone filled with the fluid flow. Heat and mass transport through this nanofluid is done by the convection mode of heat transfer. The impacts of microorganisms, chemical processes, thermal radiation, minimal amount of energy, and magnetic field are also considered in the mathematical model of flow problem. The Casson nano-fluid governing equations are interpreted in cylindrical coordinates. By implementing proper similarity transformations, the modeling PDEs of energy, momentum, concentration, and microorganism density are transformed into non-linear ODEs. A set of non-linear ODEs that deals with the distributions of temperature, velocity, concentration, and motile microorganisms produced by this technique. MATLAB in-built ‘bvp4c‘ technique is utilized to solve these equations. Findings are displayed graphically and elaborated theoretically. The primary goal of this work is to examine the effects during the rotation of the disc and cone as well as the impacts of other variables on the rotation. The nano-fluid temperature and radial velocity are found to be negatively impacted by the rotation parameter whereas azimuthal velocity is positively impacted. The parametric values are taken as 0.1

    (Elsevier, 2024) Farooq, Umar; Basit, Muhammad Abdul; Noreen, Sobia; Fatima, Nahid; Alhushaybari, Abdullah; El Din, Sayed M.; Imran, Muhammad
    Aims: In the current study, the flow of Carreau nano-fluid through the stretched cylinder is subject to the influences of activation energy and heat source/sink with the Cattaneo-Christov heat fluxes model studied. Applications in recent times are the purpose of better heat and mass transport nanoparticles used for this purpose because of their better thermal conductivity than normal fluids. Nanofluids are used in medicines like agricultural sprays and with time it is used in the microprocessor for cooling and also used in the refrigeration industry as coolant. Methodology: The mathematical model was developed by taking these things into account and getting a model of nonlinear partial differential equations for administering this problem. These governing equations system modified into a system of ODE by utilizing appropriate similarity transform. For numerical computation or simulation, the 'bvp4c' built-in package of MATLAB is used to implement the shooting technique. Smooth implementation took place by introducing a set of variables to make our system dimensionless. Results/Conclusion: Graphical representation depicts the profiles of concentration, velocity, thermal, and microorganism density, and the impacts of various modeling quantities on these profiles are also discussed and elaborated. In tabular analysis, a contrast of computed outcomes with the previously available outcomes shows the accuracy of our computed results at different values of physical parameters. The presence of motile microorganisms improved the heat transfer rate. (c) 2023 THE AUTHORS. Published by Elsevier BV on behalf of Faculty of Engineering, Ain Shams University.
