Non-Newtonian Electrically Conducting Nano Fluid Heat and Mass Transfer Analysis Over a Vertical Cone with Convective Boundary Condition

Electrically conducting, thermally radiative non-Newtonian Nano fluid heat and mass transfer features over a vertical permeable cone with chemical reaction and convective boundary condition is numerically scrutinized in this article. The system of transformed mathematical equations are numerically solved by utilizing the most efficient Finite element method. Brownian motion, Magnetic field, Lewis number, Biot number, Chemical reaction, Buoyancy ratio, Suction/Injection, Prandtl number, Thermal radiation parameters influence on Nanoparticle volume fraction, temperature and velocity scatterings is evaluated and the outcomes are plotted through graphs. Furthermore, the non-dimensional rates of concentration and heat transfer values are also premeditated. The temperature of the Nano fluid amplifies with rising values of Brownian motion parameter and this augmentation is more in non-Newtonian case than the Newtonian case. Addition of Convective boundary condition into the liquid flow intensifies the rates of heat transfer of non-Newtonian nanoliquid.

Steady of Thermal and Concentration Effect on a Fully Developed Jeffrey Fluid with Baffle in a Vertical Passage

The consistency of the hot effect and concentration on Jeffrey’s fully developed fluid in the vertical passage was examined. We considered two circuits by using a small, efficient aircraft. The more complex ruling ODE is solved by taking the right boundary and co-operative conditions in complex areas. The results are illustrated in a variety of important parameters and are illustrated to analyze important aspects of the results in all confusing areas. It is concluded that the stimulus in the Jeffrey parameter increases the flow rate, temperatures and concentration while the chemical reaction parameter suppresses the flow of fluid in all complex areas. The solutions obtained are compared to DS solved valued and the results hold good consistency. The current results are well supported by the current study of the specific conditions of the mathematical model.

Analysis of Unsteady Magnetohydrodynamic 3-D Rotating Flow and Transfer of Heat in Carbon Nanotube-Water Nanofluid: An Engineering Application

We have analysed unsteady Magnetohydrodynamic (MHD) 3-D rotating flow of Carbon Nanotube (CNT) water nanofluid past a stretching surface dealing with thermal radiation mechanism of heat transfer and heat source/sink. The mathematical model consists of a system of non-linear coupled Partial Differential Equations (PDEs). Numerical solution is obtained and discussed in detail. The influence of flow dominant parameters on the temperature profiles and flow-field are also discussed in detail using tables and graphs. Results are justified by previously published results in the limiting sense. Various crucial results are obtained, for example, unsteadiness parameter accelerates the fluid velocities in both directions near the sheet and reverse behaviour is noticed away from the sheet. However, fluid rotation causes reduction in primary velocity but it tends to accelerate secondary velocity near the sheet. Insertion of nanoparticle volume fraction intensifies fluid velocity and attenuates fluid temperature. We also found that multi-Walled Carbon Nanotubes (MWCNTs) offer more resistance for primary skin friction and less resistance for secondary skin friction when compared with Single-Walled Carbon Nanotubes (SWCNTs).

Numerical and Statistical Analysis of Dissipative and Heat Absorbing Graphene Maxwell Nanofluid Flow Over a Stretching Sheet

This paper is basically devoted to carry out an investigation regarding the unsteady flow of dissipative and heat absorbing hydromagnetic graphene Maxwell nanofluid over a linearly stretched sheet taking momentum and thermal slip conditions into account. Ethylene glycol is selected as a base fluid while graphene particles are considered as nanoparticles. The highly nonlinear mathematical model of the problem is converted into a set of nonlinear coupled differential equations by means of fitting similarity variables. Further, Runge-Kutta Fehlberg algorithms along with the shooting scheme are instigated to analyse the numerical solution. The variations in graphene Maxwell nanofluid velocity and temperature owing to different physical parameters have been demonstrated via numerous graphs whereas Nusselt number and skin friction coefficients are illustrated in numeric data form and are reported in different tables. In addition, a statistical method is implemented for multiple quadratic regression estimation analysis on the numerical figures of wall velocity gradient and local Nusselt number to establish the connection among heat transfer rate and physical parameters. Our numerical findings reveal that the magnetic field, unsteadiness, inclination angle of magnetic field and porosity parameters boost the graphene Maxwell nanofluid velocity while Maxwell parameter has a reversal impact on it. The regression analysis confers that Nusselt number is more prone to heat absorption parameter as compared to Eckert number. Finally, the numerical findings are compared with those of earlier published articles under restricted conditions to validate the numerical solution. The comparison of numerical findings shows an excellent conformity among the results.
