Abstract

This article investigates unsteady magnetohydrodynamic (MHD) mixed convective and thermally radiative Jeffrey nanofluid flow in view of a vertical stretchable cylinder with radiation absorption and heat; the reservoir was addressed. The mathematical formulation of Jeffrey nanofluid is established based on the theory of boundary layer approximations pioneered by Prandtl. The governing model expressions in partial differential equations (PDEs) form was transformed into dimensionless form via similarity transformation technique. The set of nonlinear nondimensional partial differential equations are solved with the help of the homotopic analysis method. For the purpose of accuracy, the optimizing system parameters, convergence, and stability analysis of the analytical algorithm (CSA) were performed graphically. The velocity, temperature, and concentration flow are studied and shown graphically with the effect of system parameters such as Grashof number, Hartman number, Prandtl number, thermal radiation, Schmidt number, Eckert number, Deborah number, Brownian parameter, heat source parameter, thermophoresis parameter, and stretching parameter. Moreover, the consequence of system parameters on skin friction coefficient, Nusselt number, and Sherwood number is also examined graphically and discussed.

3. Simulations and Convergence Analysis

The analytical homotopic analysis method/technique is a computational algorithm mostly utilized to obtained convergence solutions of highly nonlinear ordinary/partial differential equations. For convergence solutions of Equations (8)–(10), we employed the HAM algorithm. Following are the unique distinctions of this algorithm. A detailed description can be found in [39,40,41].

• This algorithm is self-determining of any larger/smaller change;
• The convergence analysis of the established systems can be authenticated smoothly;
• Further, this algorithm delivers additional ordinary authentication to choose guess functions with linear operators.

The $\hslash —\mathrm{curves}$, in homotopic analysis method, play a vital for convergence criteria for the nonlinear flow equations given in Equations (8)–(10). For that purpose, we unveiled $\hslash —\mathrm{curves}$ in Figure 2, Figure 3 and Figure 4. The parallel parts in these figures signify the acceptable approximations of variables ${\hslash }_U$, ${\hslash }_T$ and ${\hslash }_C$. We noticed that $0.5\le {\hslash }_C\le 3.5$, $-0.5\le {\hslash }_T\le 0.5$ and $0.0\le {\hslash }_C\le 0.2$.

4. Graphical Results and Analysis

In this segment, we considered the set of nonlinear differential flow laws given in Equations (8)–(10) subject to boundary conditions in Equation (11) are solved by employing an analytical algorithm called homotopic analysis method (HAM). This is a multipurpose computational algorithm mostly employed for highly nonlinear problems in modern scientific analysis, which includes various problems in mass heat transfer, electrical systems, engineering and many other scientific fields. The salient features $\mathrm{Gr},\mathrm{Ha},\mathrm{Ec},{\mathsf{\beta },\mathsf{\beta }}_1,\mathsf{\lambda },N_b,\mathrm{Sc},A_0,N_t\mathrm{and}\mathrm{Pr}$ against the Nusselt number $\left(N{u}_x\right)$, velocity $U\left(t,x,r\right)$, thermal distribution $T\left(t,x,r\right)$, the Sherwood number $\left(S{h}_x\right)$ and solutal distribution $C\left(t,x,r\right)$ are explained in Figure 5, Figure 6, Figure 7, Figure 8, Figure 9, Figure 10, Figure 11, Figure 12, Figure 13, Figure 14, Figure 15, Figure 16, Figure 17, Figure 18, Figure 19, Figure 20, Figure 21, Figure 22 and Figure 23.

Figure 5 depicts variations in the velocity $U\left(t,x,r\right)$ profile subjected to Grashof number $\left(\mathrm{Gr}\right)$. This figure discloses the direct relation of $\left(\mathrm{Gr}\right)$ with the bouncy force. As the anticipated velocity $U\left(t,x,r\right)$ rises, subject to increment in $\left(\mathrm{Gr}\right)$. The attributes of $\left(\mathrm{Ha}\right)$ on $U\left(t,x,r\right)$ are disclosed in Figure 6. As clearly, reported in this graph that the Hartmann number is directly linked with the Lorentz force greater the magnitude of the $\left(\mathrm{Ha}\right)$ produces more resistance to fluid flow due to which velocity profile shown decreasing behavior. The attributes of $\left(\mathsf{\lambda }\right)$ are exposed in Figure 7. Here, we noticed that lower $U\left(t,x,r\right)$ velocity subject to increment in $\left(\mathsf{\lambda }\right)$. Figure 8 depicts variations in velocity $U\left(t,x,r\right)$ profile subjected to stretching parameter $\left(A_0\right)$. This figure discloses $U\left(t,x,r\right)$ augmentation for higher values of $\left(A_0\right)$. Figure 9 depicts variations in velocity profile $U\left(t,x,r\right)$ subjected to Deborah number $\left(\mathsf{\beta }\right)$ This figure unveils $U\left(t,x,r\right)$ augmented for higher $\left(\mathsf{\beta }\right)$. It was noticed that lower $\left(\mathsf{\beta }\right)$, material acts in a more fluid-like way, with an associated Newtonian fluid. In contrast, larger $\left(\mathsf{\beta }\right)$, material behavior as a non-Newtonian regime, gradually dominated by elasticity and demonstrating solid-like behavior. The thermal field $T\left(t,x,r\right)$ curves for the heat-source parameter $\left({\mathsf{\beta }}_1\right)$ are unveiled in Figure 10. One can observe that temperature $T\left(t,x,r\right)$ distribution is a growing function of $\left({\mathsf{\beta }}_1\right)$. Figure 11 elucidates the consequence of Eckert’s number $\left(\mathrm{Ec}\right)$ on $T\left(t,x,r\right)$ temperature distribution. As anticipated, that $T\left(t,x,r\right)$ upsurges subject to increment in $\left(\mathrm{Ec}\right)$. The input of $\left(N_b\right)$ on $T\left(t,x,r\right)$ is evaluated through Figure 12. The temperature distribution diminishes when Brownian motion $\left(N_b\right)$ upsurges. Hence, $T\left(t,x,r\right)$ dwindles. Figure 13 delineates the thermophoresis $\left(N_t\right)$ parameter effect against temperature $T\left(t,x,r\right)$. Hence, an increase in $\left(N_t\right)$ consequently $T\left(t,x,r\right)$ escalates fluid temperature. The contribution of $\left(\mathrm{Pr}\right)$ on $T\left(t,x,r\right)$ was evaluated through Figure 14. Thermal boundary layer diffusivity upsurges when $\left(\mathrm{Pr}\right)$ augmented. Hence, Prandtl number enhances the temperature $T\left(t,x,r\right)$ boundary layer. The attributes of $\left(N_b\right)$ and $\left(N_t\right)$ effects $U\left(t,x,r\right)$ are delineated in Figure 15 and Figure 16. These figures confirm that concentration $C\left(t,x,r\right)$ profile diminishes subject to large values $\left(N_b\right)$, while the reverse effect is are found in $U\left(t,x,r\right)$ profile when $\left(N_t\right)$ thermophoresis enlarged. The contributions of the Schmidt number $\left(\mathrm{Sc}\right)$ on the concentration $U\left(t,x,r\right)$ profile are analyzed in Figure 17. As (Sc) is delineated as the ratio of kinematic viscosity to mass diffusivity, it is perceived as boosting through larger (Sc). Consequently, escalates fluid viscosity, due to which decaying in $U\left(t,x,r\right)$ noticed.

Figure 18, Figure 19 and Figure 20 highlight $\left(N_b\right)$, $\left(N_t\right)$ and $\left(\mathrm{Ha}\right)$ impact on $\left(N{u}_x\right)$. Here, in Figure 18 $\left(N{u}_x\right)$ diminishes as $\left(N_b\right)$. However, it is perceived that dimensionless heat transfer rate enhances boots through larger $\left(N_t\right)$ and $\left(\mathrm{Ha}\right)$. Figure 19 and Figure 20 reports the effects of $\left(N_b\right)$ and $\left(N_t\right)$ against $\left(N{u}_x\right)$. As anticipated, $\left(N{u}_x\right)$ enhances for large $\left(N_b\right)$ and $\left(N_t\right)$. The attributes of $\left(N_b\right)$, $\left(N_t\right)$ and $\left(\mathrm{Sc}\right)$ are disclosed in Figure 21, Figure 22 and Figure 23 against $\left(S{h}_x\right)$. Clearly noticed that in Figure 21 $\left(S{h}_x\right)$ diminishes for escalating values of $\left(N_b\right)$ and reverse behavior are found for $\left(N_t\right)$ and $\left(\mathrm{Sc}\right)$ displayed in Figure 22 and Figure 23.

5. Conclusions

The frequent engineering utilizations in designing several engineering products, cooling processes and many other fields. The non-Newtonian Jeffrey nanofluid gained a serious attraction of researchers to analyzed Jeffrey fluid with different aspects and geometry. The constitutive nonlinear PDEs for mass conservation, momentum and energy are changed to dimensionless form by utilizing appropriate set transformation variables. Further, these equations are solved with an efficient and validated algorithm analytically. This investigation gives valuable scope to researchers and engineers who deal with different non-Newtonian nanofluids. Significant outcomes of this work are:

• It is pointed out that both Grashof number and heat source parameter escalating velocity profile;
• Velocity profile diminished for larger Hartmann number;
• The thermal field augmented as Eckert number and thermophoresis enhanced and diminished for larger Brownian motion parameter;
• We found a lower concentration profile subject to a larger Schmidt number; however, a reverse trend is found for the thermophoresis parameter;
• Momentum and thermal boundary layers are extensively affected by the resistive Lorentz force; therefore, this resistive force effectively controls the momentum boundary layer of Jeffrey nanofluid;
• Undergoing investigations are fruitful for designing heat exchanger equipment and metallurgical processes.
