I am analyzing transition point over NACA 4412 airfoil at low Reynolds number using Transition Kw-SST model. I am using FLUENT for simulation. I dont know how to plot Shape factor from FLUENT result. I know that Shape factor can be calculated using the relation
where H is the shape factor, is the displacement thickness and θ is the momentum thickness.The definition of displacement thickness, δ for incompressible flow is
Where and are the density and velocity in the 'free stream' outside the boundary layer, and is the coordinate normal to the wall.


The definition of Momentum thickness for incompressible flow is

I read in a post that velocity profile can be obtained by creating a line perpendicular to the surface at the point of interest. and with the help of that line velocity variation can be plotted.



I don't know how to plot shape factor in fluent. Can anybody please help me in this regard.
