Relationship between rotational velocity and torque question.
 

I currently modelling a tidal turbine in fluent. My question is when i increase the rotational velocity of the turbine should I see an increase in the torque output of the turbine or a decrease in the torque output. Shown below is a screenshot of velocity magnitude where the rotaional velocity of the turbine is set at 0.6 rad/s.
