Hi to all,

I drew the airfoil pressure coefficient distribution diagram as shown below in Fluent:

 

 

Then I export it as a text file and opened it in Excel software. I drew it in Excel, as shown below, the lines are placed on top of each other, and the irregularity can be seen in it:

 

 

What is the problem and what should I do to have a correct and regular curve?

Thanks in advance

Regards

Hello Aras, 

the points are not ordered, so I would suggest plotting using only the markers and suppressing the lines.

To present the results, the pressure coefficient distribution should be plotted by lines.

Well then you will have to order the points. That is an Excel issue.

This is not Excel's problem, but Fluent's problem, which does not export the points in order.

In the papers, the pressure coefficient distribution curve is displayed by a line. How did they do this?

How did you create the surface you're plotting on? Fluent does export the points in order, and they must be in order or your first image would also be a mess.
