FLUENT - Steady Flow Past a Cylinder - Step 6

Step 6: Analyze Results

Plot Velocity Vectors

Let's plot the velocity vectors obtained from the FLUENT solution.

Display > Vectors

Set the Scale to 14 and Skip to 4. Click Display.

From this figure, we see that there is a region of low velocity and recirculation at the back of cylinder.

Plot Pressure Coefficient Contours

Let's take a look at the Pressure Coefficient variation around the cylinder.

Display > Contours

Under Contours of, choose Pressure.. and Pressure Coefficient. Select the Filled option. Increase the number of contour levels plotted: set Levels to 100.

Click Display.

Because the cylinder is symmetry in shape, we see that the pressure coefficient profile is symmetry between the top and bottom of cylinder.

Plot Stream Function

Let's take a look at the Pressure Coefficient variation around the cylinder.

Display > Contours

Under Contours of, choose Velocity.. and Stream Function. Deselect the Filled option. Click Display.

Enclosed streamlines at the back of cylinder clearly shows the recirculation region.
