The effects of MHD flow and heat transfer for the UCM fluid over a stretching surface in presence of thermal radiation
Summary: An analysis is performed to investigate the effect of MHD and thermal radiation on the two-dimensional steady flow of an incompressible, upper-convected Maxwells (UCM) fluid in presence of external magnetic field. The governing system of partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations and is solved numerically by efficient shooting technique. Velocity and temperature fields have been computed and shown graphically for various values of physical parameters. For a Maxwell fluid, a thinning of the boundary layer and a drop in wall skin friction coefficient is predicted to occur for the higher elastic number which agrees with the results of \textit{T. Hayat} et al. [Int. J. Heat Mass Transfer 50, No. 5--6, 931--941 (2007; Zbl 1124.80325)] and \textit{K. Sadeghy} et al. [Int. J. Non-Linear Mech. 41, No. 10, 1242--1247 (2006), \url{doi:10.1016/j.ijnonlinmec.2006.08.005}]. The objective of the present work is to investigate the effect of elastic parameter \(\beta\), magnetic parameter \(Mn\), Eckert number \(Ec\), Radiation parameter \(N\), and Prandtl number \(Pr\) on flow and heat transfer characteristics.
