“…In this problem, the authors have determined a dual solution for shrining sheets while a single solution for stretching sheets. Santhi et al [35] have used the stretched sheet to discuss the nanofluid flow with the influence of chemical reaction and NPs of alumina and titanium oxide. The analysis of stability for MHD NPs past stretching as well as the shrinking surface has been carried out with the effects of square velocity term by Zainal et al [36].…”

In this investigation, a 2D flow of micropolar hybrid nanofluid (HNF) is considered over stretching/shrinking sheet. The magnetic effect is employed in a perpendicular direction to the surface of sheet. To improve the thermal conductivity of the fluid flow, the nanoparticles (NPs) of iron oxide and graphene oxide are mixed with water to obtain the HNF and water is used as a base fluidfalse(Fnormale3normalO4+GO/normalH2Ofalse)$\;( {{\rm{F}}{{\rm{e}}_3}{{\rm{O}}_4} + {\rm{GO}}/{{\rm{H}}_2}{\rm{O}}} )$. The proposed equations of the modeled problem are converted to dimensionless form by implementing the similar variables. The analytical solution of the modeled equations is evaluated by mean of homotopy analysis method. The impacts of the embedded constraints on the HNF flow profiles are discoursed theoretically by incorporating a graphical view. Special cases (stretching, shrinking) are considered for the HNF in order to examine the impacts of the embedded parameters on the HNF flow profiles. The results showed that the expanding values of the stretching parameter, the HNF flow particles are pushed in a forward direction due to which fluid moves swiftly for both shrinking/stretching cases. The velocity profiles are increased with the increasing material parameter for the stretching case, while a reducing impact is found for the shrinking case. Also, the increasing material parameter enhances the microrotation profiles the HNF flow. Furthermore, the material parameter shows the same behavior for both stretching and shrinking cases. The increasing volume fraction of the solid NPs reduces the velocity profiles for stretching case, while augments for shrinking case. On the other hand, it is observed that the increasing volume fractions of the NPs increase the microrotation and temperature profiles for both stretching and shrinking cases.

“…The researchers determined that momentum and thermal boundary layer thicknesses are directly related to buoyancy ratio parameters. A radiative hybrid nanofluid that undergoes a chemical reaction on a stretching surface was researched by Santhi et al (2020). Magnetic field parameters were inversely linked to skin friction coefficients, Nusselt, and Sherwood numbers.…”

This analytical analysis examines the MHD micropolar fluid flow and mixed convection features using entropy production analysis of an inclined porous stretching sheet. Flow field and heat transfer analysis are presented to consider thermal radiation, heat source/sink, Lorentz, and buoyancy forces. The PDEs system is transformed by appropriate similarity variables, turned into a system of high non-linearity coupling ODEs, and then solved with the help of an analytical approach. An analytical approach can provide exact explicit solutions for the flow field, heat transport, entropy production, the local skin friction coefficient, the local couple stress coefficient, and the local Nusselt number. It is shown that the magnetic field, mixed convection, and sheet inclination effects can be incorporated together into a single parameter, which is called the magneto-buoyancy-inclination parameter here. In other words, this parameter controls the boundary layer flow. In addition, an experimental procedure called Box-Behnken design (BBD) was employed to analyze the influence of material (K), radiation (Rd), and buoyancy (Λ) parameters on entropy production in MHD micropolar fluid flow over the sheet. In order to estimate accurately the optimum entropy generation containing K, Rd, and Λ, we used a quadratic regression model. Based on the results of this investigation, the value of the entropy generation number became larger by decreasing the magneto-buoyancy-inclination parameter. Further, the magnitude of the local couple stress coefficient is reduced as the heat source parameter increases.

In this study, water is apprehended as conventional fluid with the suspension of two types of hybrid nanoparticles, namely, single-walled CNTs (SWCNTs) and multiwalled CNTs (MWCNTs). The influence of a magnetic field, thermal radiation, and activation energy with binary chemical reaction has been added to better examine the fine point of hybrid nanofluid flow. The mathematical structure regarding the physical model for hybrid nanofluid is established and then the similarity variables are induced to transmute the leading PDEs into nonlinear ODEs. These equations were solved using the shooting technique together with RKF 4-5th order for various values of the governing parameters numerically. The results of prominent parameters were manifested through graphs and tables. The results indicate that the hybrid nanofluid SWCNT − MWCNT / water is fully adequate in cooling and heating compared to other hybrid nanofluids. In addition, the rise in the value of activation energy E upsurges the nanoparticle transfer rate of hybrid nanofluid.
