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.

This paper investigates the influence of carbon nanotubes to improve heat transmission with Maxwell nanofluids which is suspended in kerosene oil. This mathematical model has been expressed in terms of partial differential equations, which are transformed by using compatible variables into ordinary differential equation's. The result of this model has been attained numerically via RK fourth order with shooting iteration. The results show that with a larger magnetic field, heat transfer increases radiation while decreasing velocity. The combined electrical magnetohydrodynamic effects have the potential to improve fluid flow rates. Moreover, the non-linear radiation case is dominating to the linear case. This theoretical study may be applied in material science, purification technologies, optics and electricity owing to their astonishing possessions, aerospace industry and many more. Especially in aerospace, by way of the aid in plummeting the weight, satellite weight lessening, lightning protection for aircraft and so on.

In this manuscript, numerical and semianalytical solutions of electroosmotic flow of fractional Oldroyd‐B fluid through a vertical microchannel filled with a porous medium have been investigated. The fractional Cattaneo model is used to alter the energy equation. The Laplace and finite Fourier sine transforms have been used to get the semianalytical solutions as well as the finite difference method as a numerical solution. The results show that there is an excellent agreement between the two solutions. Moreover, the surge in velocity, flow rate, and heat transfer is extremely noticeable at the beginning of the time interval for various physical characteristics. Furthermore, as time passes, this phenomenon will reduce, and they will attain a steady state. Due to the existence of a different distribution of charges in the EDL at the channel walls, the velocity profile becomes asymmetric.
