Step 6: Analyze Results

Mach Number Plot

As in the previous tutorials, we are going to plot the velocity along the centerline. However, this time, we are going to use the dimensionless Mach quantity.

...

Then, load the mach_1D.xy by clicking on Load File....

Click Plot.

Save this plot as machplot.xy by checking Write to File and clicking Write....

Pressure Contour Plot

Sometimes, it is very useful to see how the pressure and temperature changes throughout the object. This can be done via contour plots.

...

We want this at a fine enough granularity so that we can see the pressure changes clearly. Under Levels, change the default 20 to 40. This increases the number of lines in the contour plot so that we can get a more accurate result.

Notice that the pressure on the fluid gets smaller as it flows to the right, as is consistent with fluid going through a nozzle.

Temperature Contour Plot

Now we will plot the temperature contours and see how the temperature varies throughout the nozzle.
