Figure 2 Electricity transmission tower
Consider 2D, incompressible, steady flow in a vertical channel at a Reynolds number of 100. This channel flow is
shown schematically in the figure below. The figure is not drawn to scale. NEGLECT GRAVITY for the sake of
simplicity. Channel lengthl and width w are 10 m and 1 m, respectively, as shown in the figure. Assume thickness=
1 m in the z-direction. The velocity is constant at the inlet, in the y-direction and equal to 1 m/s. The Reynolds
number is defined as
Re=
pow
fl
where is the average velocity at any cross-section. Take p = 1 kg/m3 and adjust to get the desired Reynolds
number. The absolute pressure at the outlet is 1 atm. Note that the cross-section is a square of 1m by1m. Contrast
this to the laminar pipe flow considered earlier where the cross-section was circular. When the cross-section is
square or rectangular, this type of a flow is referred to as a channel flow. When the cross-section is circular, the
corresponding terminology is pipe or tube flow.
