Steady mixed convection stagnation-point flow of upper convected Maxwell fluids with magnetic field

摘要: The steady MHD mixed convection flow of a viscoelastic fluid in the vicinity two-dimensional stagnation point with magnetic field has been investigated under assumption that obeys upper-convected Maxwell (UCM) model. Boundary layer theory is used to simplify equations motion, induced and energy which results three coupled non-linear ordinary differential are well-posed. These have solved by using finite difference method. indicate reduction surface velocity gradient, heat transfer displacement thickness increase elasticity number. trends opposite those reported literature for second-grade fluid. gradient enhanced buoyancy parameters. increases Prandtl number, but decreases.
