third-grade fluid flow of stretching cylinder with heat source/sink

In this research, the impact of heat transfer on mixed convection steady thirdgrade fluid flow over an impermeable stretching cylinder with heat source is scrutinized. the investigation of mixed convection with nonnewtonian fluid is significant in geophysical and engineering fields. appropriate transformations are alleged to obtain ordinary differential equations, which are later computed by using an analytical approach called the homotopy analysis methodology (ham), and the interval of convergence is computed. local nusselt number and coefficient of skin friction values are computed numerically for novel parameters.
