“…The model parameters were determined by a nonlinear least-squares method of fitting four material functions. The theoretical framework for studying high viscous fluid like blood had been outlined by Chhabra and Dhingra [19], Machireddy and Naramgari [39], Nimma and Naikoti [50], Nagasantoshi et al [49], Prasannakumara et al [56], Jamalabadi et al [33], and Animasaun and Pop [9].…”

The dynamics of blood conveying gold nanoparticles (GNPs) are helpful to the health workers while air conveying dust particles over rockets is helpful to space scientists during the testing phase. However, little is known on the significance of thermal diffusivity in these aforementioned cases. In this report, the partial differential equation suitable to unravel the implication of increasing partial slip and viscous dissipation on the dynamics of the mixture of (i) blood and nano size of GNPs (ii) air and dust particles on an object with an increasing diameter (uhspr) is investigated. The density, zero shear rate viscosity, heat capacity, and thermal conductivity treated in this study vary with volume fraction nanoparticles. In the second case, the interaction between the solid particles and air is incorporated into the momentum equation using the Stokes drag. Transformation and parametrization of the two‐dimensional nonlinear partial differential equations were obtained with the aid of suitable similarity variables. Thereafter, the numerical solutions of the corresponding boundary valued problems were obtained using the classical Runge–Kutta integration scheme together with shooting techniques and Matlab bvp5c package. Enhancement in the rate of viscous dissipation is a major factor suitable to increase the velocities of both fluids, boost temperature distribution across both fluids, and local skin friction coefficients. There exist a significant difference between the effect of partial slip on the dynamics of blood‐gold nanofluid and dusty fluid.

“…Micropolar fluid moving past a linearly stretchable region was studied by Reddy and Krishna [10] for Soret-Dufour mechanisms in an electrically conducting MHD micropolar system. Nanofluid moving in a stretchable region with a nonconstant heat source and variable viscosity was studied by Nagasantoshi et al, [11]. Lakshmi et al, [12] performed a numerical study of MHD flow past a moveable upright penetrable plate with heat and mass transport.…”

This study is unique in that it considers both the magnetic field and the electromagnetic force in the flow direction. The imposed magnetic field causes the fluid flow to slow down, whereas the electric force factor increases the fluid velocity and temperature.The principle aim of the present study is addressing electro-hydrodynamic blood-based hybrid nanofluid behaviour when it passes through a vertical stretchable areas.The theories of the Cattaneo-Christov model were investigated with thermal radiation possessing heat generation in this study. Partial differential equations were used to solve the problem. To look into systems of coupled nonlinear differential equations, the set of equations was simplified using appropriate variables. The answer to simplified equations is obtained using a novel numerical method known as the Spectral relaxation method (SRM). Because it can decouple and linearize the set of equations, the SRM is preferred. The SRM uses the Gauss-Seidel approach as itsfoundation. The analysis of equations were done numerically utilizing spectral relaxation techniques. The outcomes are (i) Higher electric field factor is noticed to enhance both velocity and temperature profile; (ii) Increase in Eckert number is observed to increase both thermal and hydrodynamic boundary layer thickness; (iii) A higher value of K extends the hole and allows for higher fluid flow by increasing the fluid velocity; (iv) Increase in Pr depreciates both velocity and temperature profile; and (v) A higher value of Sc depreciates the skin friction and Sherwood number

This study investigates flow of non-Newtonian fluid containing nano particles and gyrotactic micro-organisms on stretching surface considering magnetic factor and thermal radiations. Cattaneo-Christov model is employed to analyze flow characteristics. The governing Partial Differential Equations (PDEs) along with associated boundary conditions describing the model are converted into Ordinary Differential Equations (ODEs) by suitable transformations. Homotopy Analysis Method (HAM), a semi-analytic solution technique is employed to obtain the solutions. The inspiration of important embedding variables on velocity, temperature, and concentration profiles are presented in tabular and graphical form to elaborate flow properties. It is deduced that the convective parameter and Weissenberg number, both have positive effect on dimensionless velocity whereas buoyancy ratio factor, bio-convective Rayleigh number, and magnetic force have inverse relationship with velocity profile. The presence of radiations and Brownian motion parameter boost energy transfer while it diminishes for higher Prandtl number values and mixed convection factor. Concentration intensifies for larger Prandtl number, activation energy, and thermophoresis parameters whereas it decreases for increasing temperature difference, Brownian motion, Schmidt number, and mixed convection factor. Bio-convective Peclet number, Lewis number, and microorganism concentration gradient factor, all depreciate microorganism concentration panel.
