Blasius velocity profile
WebObjectives. The main objective of this example is to obtain the laminar boundary layer velocity profile on a moving flat plate. Here, the plate is moving at a constant velocity of 1 m/s. The quiescent fluid surrounding the flat plate is air. Through this example, you will also learn how to set up the MRF model in Ansys Fluent. WebMay 2, 2024 · Fig 8.3 Blasius solution to steady laminar flow over a flat plate. ... With an altered velocity profile the velocity gradient at the surface also changes indicating that the surface stress changes. The link between pressure gradient and surface stress can be very complex, influenced by the conditions that result in a specific pressure gradient. ...
