“…Combining a well-known numerical 'Runge-Kutta fourth' (RK-IV) technique with the shooting methodology in Mathematica-10 makes it feasible to solve the system governing the equations (10)- (13). The numerical solutions to the ordinary differential equations (10)-( 13) are found by using the shooting approach and the RK-IV method.…”

“…The estimations of the control parameters have been updated so that they are consistent with the tables and figures. The selection of these values is directed by the far-field boundary criteria (12)(13). Researchers [15] suggested that nanofluids with a concentration of more than 5% to 6% of nanoparticles may exhibit non-Newtonian fluid behavior so the volume fraction of titania is determined within the range of 0.005, 0.03 .…”

The purpose of this study is to evaluate the effects that aggregation of nanoparticles has on mixed convective stagnation point flow and porous media across a permeable stretched vertical Riga plate in the occurrence of a heat source or sink for ethylene glycol-based nanofluids. It is possible to evaluate nanoparticle aggregation with modified versions of the Krieger-Dougherty and Maxwell-Bruggeman models. To obtain numerical solutions to the mathematical model of the present issue, the Runge–Kutta (RK-IV) with shooting technique in Mathematica was used. Figures in the proposed mixed convection and suction variables along a boundary surface in the stagnation point flow towards a permeable extending Riga plate identify and explain heat transfer processes and interrupted flow occurrences. By combining titania (TiO 2) nanoparticles with ethylene glycol as the base fluid, improved heat transmission is possible. The effects of different inputs on temperature and velocity profiles, skin friction coefficient, and local Nusselt number were graphically shown using tables and graphs. The heat transmission and skin friction rates both increased when the suction parameter was given larger values. Increases in both skin friction and the Nusselt number may be attributed to variations in the volume percentage of nanoparticles. Heat source parameter increased the temperature profile and reduced the Nusselt number. Aggregation models provide more accurate velocity and skin fraction profiles than homogeneous models, which is why they are more often used. The findings were confirmed by comparing the most up-to-date research with previously published results for the same situation. Results indicated that the two sets of data were consistent with one another.

“…Khashi'ie et al [38] observed MHD hybrid nanofluid flow through the moving plate with presence of Joule heating. Recently, Rafique et al [39] reported the impact of various nanocrystal shape and irreversibility analysis for the alumina-water based nanofluid flow over the stretching sheet with quadratic velocity slip and Joule heating. They found that blade-shaped particles perform better on temperature and velocity profiles than other shapes of nanoparticles.…”

The advancement of non-Newtonian nanofluid innovation is a crucial area of research for physicists, mathematicians, manufacturers, and materials scientists. In engineering and industries, the fluid velocity caused by rotating device and nanofluid has a lot of applications such as refrigerators, chips, heat ex-changers, hybrid mechanical motors, food development, and so on. Due to the tremendous usage of the non-Newtonian nanofluid, the originality of the current study is to explore the influence of nanoparticle radii and inter-particle spacing effects on the flow characteristics of Casson Methanol-based Aluminium alloy $(AA7072)$ nanofluid through a rotating disc with Joule heating and magnetic dipole. The present problem is modeled in the form of partial differential equations (PDEs), and these PDEs are converted into ordinary differential equations with the help of suitable similarity transformations. The analytical solution to the current modeled problem has been obtained by using the Homotopy Analysis Method(HAM) and numerical solutions are obtained by employing Runge-Kutta-Fehlberg method along with shooting technique. The main purpose of the present research work is to analyze the behavior of the velocity and temperature of the nanofluid for small and large radius of the Aluminium alloy$(AA7072)$ nanoparticles and inter-particle spacing. The radial and tangential velocities are enhanced due to rising Ferro-hydrodynamic interaction parameter and the skin friction force for radial and tangential directions are enhanced $10.51\%$ and $2.16\%$ when $h=0.5$. Also. the heat transfer rate is reduced $18.71\%$ and $16.70\%$ when $h=0.5\%$ and $R_p=1.5$. In fact, the present results are compared with the published results and they met good agreement.

This work extends the previous research on electroosmotic flow in semicircular microchannels, further investigating the electromagnetic electroosmotic flow of Jeffrey fluid under the combined action of the electric field force and electromagnetic force. The analytic solution of velocity is derived using the variable separation method. The influences of oscillation Reynolds number R e , Hartmann number H a , electric width K , relaxation time D e and retardation time λ 2 ω on velocity are examined through graphical analysis. The results show that an increase in Reynolds number R e leads to stronger oscillations in the velocity profile at any Hartmann number H a , and the change in velocity oscillations becomes more pronounced with increasing Hartmann number H a . Specifically, at lower Hartmann numbers H a , the velocity increases with an increase in electric width K and relaxation time D e , but decreases with an increase in retardation time λ 2 ω . An interesting finding is that, at higher Hartmann numbers H a , the velocity of the Jeffrey fluid still decreases under the influence of obstruction in the channel. Furthermore, the results of this study are compared with those of previous scholars to validate their accuracy.
