Abstract

In various attempts, researchers considered Eyring–Powell fluid flow past a flat stretching surface supported with different physical effects, but as yet few explorations are proposed with accuracy regarding cylindrical stretching surface. In this work, we have considered magnetohydrodynamic Eyring–Powell nanofluid flow brought by an included stretching cylindrical surface under the region of stagnation point. To report thermophysical aspects, Joule heating, thermal radiations, mixed convection, temperature stratification, and heat generation effects are taken into account. The flow conducting differential equations are fairly converted into system of coupled non-linear ordinary differential equations by means of appropriate transformation. A numerical communication is made against these obtained coupled equations through shooting method supported with fifth-order Runge–Kutta scheme. It is found that fluid temperature shows an inciting nature towards Eckert number, thermophoresis parameter, Brownian motion parameter, thermal radiation parameter, and heat generation parameter, but it reflects opposite trends for Lewis number and thermal stratification parameter. Furthermore, the obtained results are validated by providing comparison with existing values which set a benchmark of quality of computational algorithm.
