Wall Temperature Plot

We will now investigate the temperature variation along the wall. To do this we need to create a new line on the simulation. It needs to be a horizontal line correponding to the wall.

...

The FLUENT result is shown in the graphics window.

Pressure Plot

Now let's us look at the pressure variation at the centerline. We can use the center-line we created earlier.

...

Now click on Data Series tap to specify the location of the chart data. Change the name of the first data series from Series 1 to FLUENT. Under Data Source, specify Centerline as Location. The centerline was already created while doing the temperature variation along the center-line. If that chart was skipped please refer to that section on how to create a centerline.

We would also like to compare our simulation result with experimental data. Experimental data is can be downloaded here. Download it to the directory that you like. Now, click a new data series Image Removed. Name it Experiment. Under Data Source, select File and browse for the downloaded experimental data.

Our purpose in this exercise is to study the pressure variation along the length of the pipe. Therefore our chart should show pressure in the y-axis and x-position in the x-axis.

In this case, our x-axis variable is x and our y-axis variable is pressure. 

We want to the chart to be displayed exactly the same way as for wall temperature and centerline temperature plots.

The FLUENT result is shown in the Graphics window.

Axial Velocity Profile

Now, let's investigate the velocity profile at different lengths along the pipe. We are especially interested in the flow development before it enters the heated section. Then please divert your attention to the difference heat addition has on flow development.
