“…The significance of rotation on the flow of nanofluid and its thermal performance is explored in the paper of Akinshilo. 40 Some more interesting articles that includes the gyratory action on MHD fluid flows under different flow configurations are due to Chamkha et al, 41 Nandi and Kumbhkar, 42 Shoaib et al, 43 and Veera Krishna. 44 Recently, Hussain 45 presented a numerical study to inspect the heat transfer behavior of MHD three-dimensional nanofluid flow over a stretching sheet with rotation effect.…”

The main goal of this presentation is to scrutinize the flow behavior of transient hydromagnetic Ti6Al4V-H2O-based nanofluid flow within a symmetric channel bounding a uniform porous medium with induced magnetic field and Hall current effects. The nanofluid is assumed to be partially ionized and its flow is influenced due to the presence of a strong transverse applied magnetic field domain. Due to this reason, induced magnetic field and Hall current impacts are focused in this study. The right surface of the channel is considered to be magnetized and oscillating vertically while the left surface is non-magnetized and stationary. The flow model is transformed to a similar model by the use of dimensionless transformations and leading resulting equations are solved analytically with the aid of variable separable method. The results are demonstrated with the assistance of Mathematica software and also validated with the existing results in the literature. This study is significant in analyzing the flow nature of highly electrically conducting nanofluids. An important flow characteristic observed from this study is that by increasing the volumetric concentration of nanoparticles in the fluid, the induced magnetic field is increased due to the rise in electrical conductivity of the fluid. Furthermore, the Hall current and magnetic diffusion brings a significant decrement in induced magnetic field along the main flow.

“…Furthermore, the rotatory fluid motion can set up natural convection due to the density variation caused by the Coriolis force. The rotatory action on MHD liquid motion is presented in the investigations of many researchers and their teams, namely Rama Mohan Reddy et al, 12 Singh et al, 13‐16 Makinde et al, 17 Chamkha et al, 18 Akinshilo, 19 Nandi and Kumbhakar, 20 Veera Krishna, 21 and Shoaib et al 22 In MHD flows, an induced magnetic field (IMF) arises for those fluids whose magnetic viscosity is very small, that is, the magnetic Reynolds number is very large. Thus, the study of the IMF effect becomes important for the working fluids whose magnetic viscosity is very small.…”

In this mathematical presentation, we examined the significance of Hall current on MHD buoyancy‐driven boundary layer flow of a Ti6Al4V‐H2O based nanofluid past a vertical surface implanted in a uniform permeable region. The vertical surface is considered to be magnetized and induced magnetic field (IMF) impacts are also considered. The nondimensional flow model is solved with the assistance of the two‐term perturbation scheme. Various results are obtained by numerical computation for different significant parameters. These results are presented and analyzed in graphical and tabular form. In the boundary layer domain, the transpiration velocity across the surface tends to diminish the main flow, IMF along the main flow, fluid temperature, and concentration. It is remarkably noted that IMF along the main flow grows for incrementing values of volume fraction coefficient of nanofluid. In the magnetic boundary layer domain, the main flow and IMF along the main flow grow with Hall current. Furthermore, it is seen that for the progressing values of magnetic Prandtl number, the main flow reduces while normal flow and IMF along the main flow is induced in the boundary layer domain.

“…In the efforts to investigate, analyze and study the mechanics of the non-Newtonian flow transport and thermal transfer numerical and analytical methods have been adopted as suitable methods of analysis by researchers over the years. 31,[41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] These methods of analysis include the differential transform method, Akbari-Ganji method, Adomian decomposition method, method of weighted residuals (Garlerkin, collocation, and least squares), homotopy analysis methods, and variation of parameter method among others. The methods listed reveal errors due to round off, guess term or initial term dependence, strong dependence on the parameter of perturbation and weak nonlinearity.…”

In this paper, the analytical investigation of non-Newtonian fluid flow through a turbine disc with a heat generation effect is considered. The flow mechanics through the turbine disc is modeled using a coupled system of higher-order partial equations, which are transformed into ordinary order utilizing proper similarity transforms. Governing models are analyzed using the variation iteration and homotopy perturbation analytical methods. As observed from the results, the study shows enhancement of heat generation for non-Newtonian fluid flow through turbine disc, reveals abating thermal distribution. More so, the graphical expression shows that heat generation improves up till mid-disc. Thereafter, an increasing trend toward the fluid injection surface is observed. Validation of analytical solutions with numerical analysis boosts confidence in this study, which may be used to provide further insights into the engineering science of non-Newtonian flow of hydraulic/lube oil in practical applications, such as hydraulic couplings.
