cross-sectional geometry model shown in Figure 2.

The dimensions given for the geometry are dimensionless as they are normalised for the

characteristic length. For this case, the characteristic length is the inlet height (in this case 1.0

unit high). Fluid enters the channel at the inlet and exits from the outlet. The normalised inlet

velocity and fluid properties that are also normalised for the characteristic length are provided

as:

1.0)

Dimensionless inlet velocity: u = 1.0 and v=0.0 (i.e., normal speed to the inlet boundary =
