Abstract:
Over the last century lots of efforts have been put in the reduction of profile drag. Boundary
layer suction is one of the effective methods to achieve this goal. A laminar boundary layer will
be stabilized preventing transition from laminar boundary layer to a turbulent one and yielding
larger areas of laminar flow, which generates less drag.
In this thesis, mathematical models for incompressible laminar steady flows of three different
non-Newtonian models with/without magnetohydrodynamic effect are developed. It is
analyzed theoretically and found that much improvement can be achieved by implementing
boundary layer suction. Moreover, slip at wall/presence of magnetic field applied normal to
main flow velocity further reduces the drag.
