Separation and reattachment of turbul= ent flow occurs as the fluid encounters a backwards facing step and eventua= lly reaches the floor. Consider the diagram below which illustrates the pro= blem.
A developed, turbulent, steady flow e= nters through an inlet, passes over a backwards facing step and then reache= s the ground. In this demonstration, an enclosure will need to be created a= round the step and air will be used as the flow material. Air will enter vi= a an inlet at the top step at a speed of 0.4 m/s, with a density of 1.23 kg= /m^2 and dynamic viscosity of 1.86e-5 Ns/m^2. From this data, the Reynold= =E2=80=99s number can be calculated to be about 5000.
