“…Tables 2 and 3 were calculated to compare the present outcomes of the skin friction C f Re s ð Þ 1=2 with published values in Mabood and Das (2016), Imtiaz et al (2016) and Imtiaz et al (2019) for several values of the curvature parameterK, the fluid parameter a 1 and the magnetic parameter M . Additionally, these two tables have shown that, the skin friction decreases as both of the magnetic which is the same results observed by Rehman and Salleh (2021) and the fluid parameters increase, whereas it increase as the curvature parameter increases. Here, the calculated percentage relative error« refers to a suitable and an excellent agreement.…”

Purpose The study aims to determine an efficiency of external magnetic field on the bacteria surrounded by thousands of magnetic magnetite nanoparticles. The interstitial nanoliquid in which an artificial bacteria swims in biological cell is utilized with variable thermal conductivity. Two dimensions unsteady motion of second grade fluid are considered. The stretching wall is taken as a curved surface pattern. Design/methodology/approach The mathematical results have been obtained by Chebyshev pseudospectral method. Findings The impact of the various governing parameters is described by numerical tables and diagrams. It is proven that the pure blood velocity curves are higher when compared with the magnetite/blood. It is demonstrated from clinical disease that dangerous tumors show diminished blood flow. This study concludes that the blood velocity profile increases by increasing the values of fluid parameters. This implies that the medication conveyance therapy lessens the tumor volume and helps in annihilating malignancy cells. The blood temperature distribution raises as the magnetite nanoparticles concentration increases. Consequently, the physical properties of the blood can be enhanced by immersing the magnetite nanoparticles. Further, the present outcomes cleared the thermal conductivity as, a variable function of the temperature, has an important role to enhance the heat transfer rate. Originality/value To the best of authors’ knowledge, this study is reported for the first time.

In this research work, we will investigate the influence of MC (Marangoni convection) in engine oil as base fluid with viscous dissipation and the influence of variable viscosity on an infinite disk. The flow system takes into account MC with influence of variable viscosity, convective boundary conditions, and viscous dissipation. Furthermore, for the sake of the present research paper, the graphical results of the temperature and velocity profiles are presented. To convert a collection of PDEs to NODEs, we applied appropriate transformations. We utilize the Homotopy analysis method to solve this set of equations. The effects of temperature and velocities on numerical perceptions involving Casson, magnetic, Schmidt number, thermophoresis, and Brownian motion input factors are shown. A physical description is used to simulate and evaluate the structures of flow features such as velocity and temperature profiles in response to changes in developing factors. It is hoped that this issue would contribute positively to improving the heat transformation ratio in order to satisfy the demands of the industrial and engineering sectors.

Objective: This paper investigates velocity profile for two-dimensional, incompressible, laminar forced convection flow of the fluid model for Prandtl-Eyring fluid past a stretching sheet in the presence of fluid parameters. Methods: The governing partial differential equation for the flow was transformed into non-linear ordinary differential equation by using the deductive one parameter group theoretic method and numerical solution of non-linear ordinary differential equation (ODE) is solved by MATLAB bvp4c solver. Findings: The solution of velocity profile obtained as a function of parameter and . The effect of the fluid parameter was discussed graphically. Novelty: The main goal of this article is to analyze boundary layer flow of Prandtl-Eyring fluid over a stretching surface. The conservation equations of mass, momentum are converted into non-linear ordinary differential equations along with boundary conditions using deductive one parameter group theoretic method and solved by MATLAB ODE solver. Comparisons with previously published works are made, and results show a high level of agreement. This type of research is applicable to extrusion, paper production, fiber glass production, hot rolling, condensation process, crystal growing, polymer sheets etc. Keywords: Boundary layer, laminar flow, Deductive one parameter Group theoretic method, Absolute invariant, Stretching Sheet, Prandtl-Eyring fluid
