harishameed33 is on a distinguished road

Ive been having trouble with the 1d virtual disk model, when i run it im struggling to get the effects of the wake of the turbine when i view velocity magnitude in a scalar scene. I have attached the screenshot of the velocity magnitude, the wake never ends and just continues.

I have used the following power curve
"wind (m/s)","power(W)","ct"
2.5,200000,1.2
5.0,500000,0.86
10.0,4000000,0.8
11.4,5200000,0.53
15,5200000,0.23

it is for 5 MW reference wind turbine.

Can anyone help please? Thanks
