In today’s era of rapid technological development, there is an increasing requirement for high-functioning investiture solutions, working liquids and materials that can satisfy the benchmarks of energy efficacy. Specifically, within the domain of heat transference-based industries, an essential challenge is to fabricate a cooling medium that can effectually cope with dissipation of substantial heat flux engendered by high-energy utilizations. At present, nanoliquids are extensively deliberated as some of the most promising aspirants for such effectual cooling mediums. The current investigation features hybrid nanoliquid flow adjacent to magnetized non-isothermal incompressible sphere. Rheological expressions representing micropolar liquid are accounted for flow formulation. The rheological analysis is developed using the boundary-layer concept. Buoyancy impact is accounted for heat transference analysis. Nanoparticles with distinct shapes are considered. The developed nonlinear systems are computed numerically and non-similar simulations are performed.

The viscoelastic materials are a famous subclass of non-Newtonian fluids that present novel applications in various industrial processes. The most famous applications of viscoelastic fluid are observed in polymer processing. A major activity of the polymer processing industry is the production of thermoplastic polymer sheets and films. However, due to distinct rheology, a complete understanding of such materials is quite necessary for the polymer process. This continuation presents the rheological features of viscoelastic fluid with heat transfer phenomenon near the oblique stagnation point flow. The induced flow is accounted via stretched cylinder. The heat transfer analysis is also taken in the presence of non-linear heat flux. The problem is formulated using cylindrical coordinates in terms of non-linear coupled partial differential equations. Similarity transformation and normalized variables are used to convert the governing system into a set of ordinary differential equations. Due to the highly nonlinear model, the analytical solution of the system seems to be impossible therefore the approximate solution is obtained using the numerically stable and convergent finite difference method known as the Keller Box scheme. The simulated data via numerical algorithm is verified after comparing with already published investigations. The streamlines for the flow problem are presented. [ABSTRACT FROM AUTHOR]

Oblique stagnation point flow of incompressible Maxwell nanofluid past a stretching cylinder with active and passive controlled nanoparticles concentration condition is discussed numerically. The suitable coordinate decomposition reduce the governing boundary layer equations into the system of nonlinear ordinary differential equations which are approximated by Keller box procedure for several values of pertinent parameters. The Numerical results are compared and validated with existing ones as particular cases and found to be an excellent agreement. Velocity profile and lines of flow are sketched to discuss the Obliqueness of the flow. The temperature and concentration profiles drawn to illustrate the influence of involved parameters also variations in local Nusselt and Sherwood numbers are presented through tabular data. It is observed that the behavior of tangential velocity for the viscoelastic fluid and concentration of nanoparticles against thermophoresis diffusion over the cylinder are quite opposite when compared with the results over flat sheet. The temperature distribution and concentration of nanoparticles decreases with elasticity of the fluid. [ABSTRACT FROM AUTHOR]
