Article Citation - Scopus: 7Numerical Evaluation for the Peristaltic Flow in the Proximity of Double-Diffusive Convection of Non-Newtonian Nanofluid Under the Mhd(Elsevier B.V., 2024) Riaz, M.B.; Hussain, A.; Saddiqa, A.; Jarad, F.This article mainly studies the 2-D propagation of a non-compressible Eyring-Powell nanofluid flow through a stretched wedge under the Magneto-hydrodynamic effect. Equations for temperature, concentration, double-diffusive convection and momentum are taken into consideration. Since solving the dimensionless equations associated with our study is an uphill task, we utilize the MATLAB bvp4c solver to illustrate the graphical performance of different parameters. This manuscript may be significant in the projects in the field of industry and medicine. The manuscript's noteworthy features include the magnetic field, heat source-sink parameter, double diffusivity, and solar radiation process. The main finding is that the local fluid parameter k1 and magnetic field parameter M decelerate the velocity of nanofluid. Because different nanoparticles have different effects on fluids, the fluid's temperature exhibits multiple behaviors, therefore by escalating the Prandtl number initially, it increases and then decelerates due to the presence of nanoparticles. The concentration of fluid declines as the Schmidt number rises. The double diffusivity of Eyring-Powell nanofluid improves with magnification in the fluid's Schmidt number Sc and Prandtl number Pr. © 2024 The Author(s)Article Citation - WoS: 11Citation - Scopus: 12Unsteady Nano-Bioconvective Channel Flow With Effect of Nth Order Chemical Reaction(de Gruyter Poland Sp Z O O, 2020) Basir, Md Faisal Md; Naganthran, Kohilavani; Azhar, Ehtsham; Mehmood, Zaffar; Mukhopadhyay, Swati; Nazar, Roslinda; Khan, Ilyas; Md Basir, Md FaisalNanofluid bioconvective channel flow is an essential aspect of the recent healthcare industry applications, such as biomedical processing systems. Thus, the present work examined the influence of nth order chemical reaction in an unsteady nanofluid bioconvective channel flow in a horizontal microchannel with expanding/contracting walls. The suitable form of the similarity transformation is exercised to transform the governing boundary layer equations into a more straightforward form of system to ease the computation process. The Runge-Kutta method of fifth-order integration technique solved the reduced boundary layer system and generated the numerical results as the governing parameters vary. It is found that the destructive second-order chemical reaction enhances the mass transfer rate at the lower wall but deteriorates the mass transfer rate at the upper wall. The upper channel wall has a better heat transfer rate than the lower wall when the Reynolds number increases.Article Citation - WoS: 20Citation - Scopus: 20Hydromagnetic Flow of Micropolar Nanofluid(Mdpi, 2020) Anwar, Muhammad Imran; Misiran, Masnita; Khan, Ilyas; Baleanu, Dumitru; Nisar, Kottakkaran Sooppy; Seikh, Asiful H.; Rafique, KhuramSimilar to other fluids (Newtonian and non-Newtonian), micropolar fluid also exhibits symmetric flow and exact symmetric solution similar to the Navier-Stokes equation; however, it is not always realizable. In this article, the Buongiorno mathematical model of hydromagnetic micropolar nanofluid is considered. A joint phenomenon of heat and mass transfer is studied in this work. This model indeed incorporates two important effects, namely, the Brownian motion and the thermophoretic. In addition, the effects of magnetohydrodynamic (MHD) and chemical reaction are considered. The fluid is taken over a slanted, stretching surface making an inclination with the vertical one. Suitable similarity transformations are applied to develop a nonlinear transformed model in terms of ODEs (ordinary differential equations). For the numerical simulations, an efficient, stable, and reliable scheme of Keller-box is applied to the transformed model. More exactly, the governing system of equations is written in the first order system and then arranged in the forms of a matrix system using the block-tridiagonal factorization. These numerical simulations are then arranged in graphs for various parameters of interest. The physical quantities including skin friction, Nusselt number, and Sherwood number along with different effects involved in the governing equations are also justified through graphs. The consequences reveal that concentration profile increases by increasing chemical reaction parameters. In addition, the Nusselt number and Sherwood number decreases by decreasing the inclination.Article Citation - WoS: 39Citation - Scopus: 38Comparative Investigation on Mhd Nonlinear Radiative Flow Through a Moving Thin Needle Comprising Two Hybridized Aa7075 and Aa7072 Alloys Nanomaterials Through Binary Chemical Reaction With Activation Energy(Elsevier, 2020) Zaib, A.; Khan, Ilyas; Baleanu, Dumitru; Sherif, El-Sayed M.; Khan, UmairThe intention of the current study is analyzing the significance of nonlinear radiation on magnetic field involving hybrid AA7075 and AA7072 alloys nanomaterials through thin needle. The scenario has been modeled mathematically by captivating the binary chemical reaction and activation energy. Similarity variables are deployed to change the system of PDE's into nonlinear ODE's and subsequently solved these equations through bvp4c solver. Influence of distinct material parameters on the velocity, concentration and temperature along with the correlated engineering features quantities such as drag force, heat and mass transfer rate are obtained and demonstrated via plots. The velocity of the liquid is declining function of magnetic field, while the temperature augments. In addition, obtained numerical results are contrasted through the available literature and appeared to be in admirable harmony. The current investigation shows the important features in solar hybrid alloy nano materials systems and aircraft technology. (C) 2020 The Authors. Published by Elsevier B.V.
