hello every one,

I am facing difficulty in plotting graph between y0.5 v/s X (spread rate/stream wise development of half with) for plane turbulent wall jet .

I have attached couture of velocity for my domain. please suggest how can i proceed for the solution is there any way to do in fluent or CFD post or I have to write UDF for this.

Not sure what you mean, but if you're trying to plot position of a region of speed if you create an isosurface of (for example velocity = 3m/s) you can plot the x & y position of that line. In 3d you'd get a surface to need to be a little more careful, in 2d it's easier. 

I would check the mesh resolution as the contour looks a little odd at the larger x values.
