“…Wubshet and Shanker [11] have informed the manipulates of magnetic area and thermal radiation on nanofluid past non-isothermal ball along extending layer by non-isothermal wall temperature in addition to non-isothermal thermal fluctuation. Recently, Wubshet and Chaluma ([12], [13], [14]) have been investigated that increasing in thermal nonlinear convection exhibits the enhancing feature on Nusselt number, skin friction coefficient, velocity fields close the outside of sphere, disk and cylinder while it shows the decreasing behaviour on thermal field. This effect happen due to higher density of the fluid which relates to lower the momentum diffusion and higher thermal diffusion close wall of sphere, disk with cylinder All the above quoted papers have been presenting the current past a flat surface, isothermal sphere,disk, cylinder.…”

The aim of this article is to analyze the impacts of Eckert, surface temperature and heat flux on two boundary layer flow of non-linear convection flow of micro-polar fluid past non-isothermal cylinder. The mathematical modeling for the flow problem has been created with suitable similarity transformation and dimensionless variable. The main nonlinear boundary value problems were reduced into mixed high order non-linear ordinary differential equations. The equations were solved using the method bvp4c from matlab software for numerous quantities of main constraints. The impacts of constraints on velocities, surface temperature and heat flux are examined and displayed through the graphs and tables. The convergence test has been maintained; for number of spots greater than apposite mesh number of spots, the precision is not affected. Moreover, a comparison with previous paper reachable in the literature has been reported and an excellent agreement is obtained. The acquiring shows that enhancing in the values of surface temperature and heat flux constraints (F, H) is to improve thermal diffusion that improve temperature distributions q(h);h(h).

“…Significance of viscous dissipation on stagnancy flow of Oldroyd-B liquid due to a Riga plate was numerically deliberated by Nayak et al 27 They confirmed the relaxation-retardation plays prominent role in escalating the thermal fields. Ibrahim and Zemedu 28 used bvp4c MatLab code to inspect the impression of magnetic field on the flow of micropolar nanoliquid triggered by a revolving disk. A similar kind of study with flow of micropolar liquid over a cylindrical pipe was carried out by Yadav and Verma, 29 they computed the simultaneous solutions for two distinct fluids.…”

This investigation is performed to deliberate the novel significance of nonlinear thermal radiation effect on magnetohydrodynamic flow of Casson hybrid nanoliquid caused by a curved stretching sheet. The flow and thermal transport nature of three different hybrid nanoliquids in the stimulus of viscous dissipation, nonlinear radiation and magnetic force is discussed numerically. The novelty of this work is to obtain the simultaneous solutions for three different types of hybrid nanoliquids, they are obtained by suspending titanium alloy (Ti6Al4vs.) is composed of titanium, aluminum and vanadium in the ratio of 90:6:4 respectively and aluminium alloy (AA7075) is compossed of Aluminum, Zinc, Magnesium and Copper nanoparticles in the ratio of 90:6:3:1 respectives with added metals Silicon, Ferrous and Magnesium. in three various working liquids viz. methanol, ethylene glycol and engine oil. The flow governing PDE's are transmuted into ODE's with suitable similarity transformation and solved by using Runge-Kutta and Newton's approach. Numerical outcomes of flow and temperature profiles are presented via graphical trends, also skin friction coefficient and rate of thermal transfer are illustrated via tabulated values. Major outcomes reveals that, inclusion of hybrid nanometer sized particles in pedestal liquid lead to an large hike in thermal transfer performance. Importantly, thermal transport rate and temperature profiles of the hybrid nanoliquid rises with improving nonlinear radiation values and these results are significant in nonlinear radiation case as compared with linear radiation case.

This paper studied the simulation of partial differential equations that model Casson fluid dynamics on a curved surface when Lorentz force, viscous dissipation, first-order chemical reaction, convection, uneven heat sink/source, and mass transmission at the wall are significant. An appropriate similarity conversion transforms the governing equations into non-dimensional ODEs. The bvp5c Matlab package is utilized to acquire the velocity, temperature, and concentration outcomes. This work aims to attain simultaneous solutions for Newtonian and non-Newtonian flow cases and analyze the reasons for deviation in flow and thermic border thicknesses. Augmenting the parametric curvature values inflates the velocity profiles and declines the thermal transmission rate. Also, the heat transport rate in the brunt of uneven heat source and viscous dissipation is extensive for non-Newtonian liquid compared with the Newtonian fluid.
