Predicting the mean velocity profile of a turbulent incompress- ible fluid flow in a channel has been one of the fundamental testbeds for turbulence models.
Within the simulations the inlets will be modeled in two ways: without forcing in flow and steady blowing. These inlets are used to control the main flow.
Secondary flow is a prominent feature of channel bends; it alters the streamwise velocity and bed shear stress distributions.
While the design project worked well as a capstone project, the constructed water channel will be used as a valuable facility in both Mechanical Engineering and.
