Laminar Flow Over a Wedge - Homework


This homework will focus on another classic example of a laminar boundary layer, which is the Falkner–Skan boundary layer flow over a 2D wedge. This problem has a Blasius-type self-similar analytical solution, but only under the assumption of a specific free-stream flow distribution. The Falkner–Skan flows can be found in biochemical processes, chemical engineering and nanofluids. In this homework, you will be guided to build a 2D CFD model to simulate the Falkner–Skan flow. In addition, you are expected to complete the visualization and analysis of velocity profiles to better understand the development of the Falkner–Skan laminar boundary layer. Comparison with the analytical profile will also be made and differences will be explained.
