Significance of ethylene glycol-based CNT Homann nanofluid flow over a biaxially stretching surface

The electromagnetically conducting flow consisting of carbon nanotubes suspension immersed with ethylene glycol is scrutinized on a surface which is stretching biaxially, planarly, and perpendicularly. Thermal analysis is conducted with the impact of heat generation and Joule heating. Furthermore, similarity ansatzes are used to obtain ordinary differential equations. The finite difference approach, bvp4c in Matlab, is utilized to determine the numerical solutions. It is noted that the temperature of the system increases because of the motional electromagnetic force induced due to magnetic field; however, velocities decline. By enhancing nanofluid volume fraction, the interactions between the particles become more chaotic and unpredictable which enhances the velocities and thermal transport. In addition, the numerical and asymptotic outcomes of horizontal stresses and local Nusselt number are incorporated for pertinent parameters. It is worth mentioning that the numerical values of temperature gradient are enhanced for a selected range of Prandtl number but decrease for Eckert numbers. This implies that the thermal conductivity is augmented for the former, whereas decayed for the latter.
