Hi Ziad, You need to define a new variable named turbulence intensity (TI) as TI = u'/U, where u' = sqrt(2/3*k) with k being the turbulence kinetic energy and U = sqrt(u_x^2+u_y^2+u_z^2). You may also need to create a plane or a line over which to plot the TI with respect to spatial coordinates.
Dear Benjamin, For this, I recommend you to watch this video on the channel: ruclips.net/video/PKTLeTJ_pcc/видео.html Keep in mind that both the thickness of the boundary layer and the thickness of the first prism layer next to the blade surface decrease from the blade root to the tip. Thus, the thickness of the boundary layer at the root of the blade is adopted for the entire blade, while the thickness of the first layer at the tip of the blade is used for the entire geometry of the blade. Respectfully, Mojtaba.

what happened to the wind that goes between the blades and not just the blade tip arc regards Graham Flowers
Love looking at it!
Looks awesome!!
Amazing!
very good!
I want to know how to plot turbulence intensity in ansys cfx

Hi, I want to know how to estimate the mesh boundary layer height for these rotating machine?
