Description
Summary:The objective of this study is to probe the effects of boundary layer flow over an exponentially stretching cylinder having nonlinear velocity placed in a porous medium. The modeled partial differential equations are transformed into nonlinear ordinary differential equations by applying suitable similarity transformations. A numerical solution is attained using the finite difference Keller–Box method. The physical parameters and skin friction coefficients are studied on the velocity profile. The fluid velocity and skin friction coefficient decrease with the increase in Re and κ, while a reverse behavior is reported for ɛ.
