Simulation of NREL UAE Phase VI turbine

i am also getting 466 N-m at 10 m/sec. I cannot figure out the reason!!!

Hi Sijal,

Keep refining the mesh in the areas just upstream and downstream of the rotor

I got this problem as well. When i refined around 24m at downstrem i started to get some results with 7% of error.

Hii i simulate a wind turbine NREL in fluent the convergence is less than 10-4 BUT pressur coef IS LESS than the experemental i use MRF steady state whith k-epselon transition . i have a mesh of (inlet 5 radi and 8 radi in outlet)2.5 million with a BL a=0.0004 and 10 element in some station i have the same pressur coef 80% 95 % but note the same in 30% 46% in 13 m/s and above
my bc in velocity inlet ti=1% and visco turbulent =5
pressur outlet in farfeild and periodic condition 180°
please help me (sorry for my english)
if you have a mesh case and data please send to malikoualger@yahoo.fr please
