8.1.8 Step 7: Analyze the Numerical Solution and Compare to Expected Results

After the solution is run to convergence, obtain a revised velocity field. The velocity magnitude contours for the parabolic inlet $x$ velocity are shown in Figure  8.1.9, and can be compared to the results of a constant velocity of 0.1 m/s (Figure  8.1.2). For the constant velocity condition, the constant profile is seen to develop as the flow passes through the duct. The velocity field for the imposed parabolic profile, however, shows a maximum at the center of the inlet, which drops to zero at the walls.
