Plot pressure distribution on a section of 3d blade

Dr.been · July 1, 2010, 23:32

My wind turbine blade has spanwise direction in z ,chordwise in x ,thicknees of airfoil in y. After simulation, I use XY plot -> pressure -> static pressure, choose monitor at z= 30% span (which i has created already with Iso-surface) to show pressure distribution over airfoil at this section.The xy plot show as the attached picture below which is very confuse for me. What should I do? Any one can help me?

So, I really need your valuable guidelines!

Sincerely yours

My guess is that you have now plotted all values on the iso-surface, whereas you are only interested at the values that are actually on the foil surface.

Perhaps you can instead create a clip surface, where you clip the foil surface from, say, 29.9 % to 30.1%. (Or maybe even 30% to 30% although I'm not sure this will work.)

Good luck!

Hi
you can do it in 2 ways:
1-opening it in tecplot and using a plane for each section
2-in Cfd Post.you should define a plane--->define a polyline at the intersection of plane and blade---->define a chart with x axis of blade's chord and y axis of pressure or somthing else at the intesection on plane and polyline which makes an airfoil that you want to have pressure chart of it
