Quadratic Polynomial Velocity Profile in Laminar Boundary Layer Thickness

Motion of fluid elements can be described by the Navier-Stokes equations. They arise from theuse of Law of motion to a fluid. In this investigation, two dimensional Navier-Stokes have beenengaged. Then they are applied to an incompressible viscous fluid movement down an inclinedplane with net flow. These leads to examining the effects to the velocity of the motion at variousangles of inclination and finding the boundary layer thickness. Viscous laminar incompressiblefluid flow also flow on an inclined position which makes it necessary to investigate the flow on aninclined plane. Results that have been achieved are of the flow over horizontal flat plate. Solutionthat has been obtained involves a flat photographic film being pulled up by a processing bathby rollers at an angle�to the horizontal. Quadratic polynomial function approximate velocityprofile has been obtained under initial boundary layer conditions. This velocity profile has beenused in momentum integral equation for flow over an inclined plane to get the boundary layerthickness. Boundary layer thickness is one of the parameters that is used to obtain the flowvelocity down inclined plane.
