{latex}$vec{v}^{\,}_r)$r${latex}

is the relative velocity (the velocity viewed from the moving frame) and

{latex}$vec{\omega}^{\,})${latex}

is the angular velocity.

In Fluent, we'll turn on the additional terms for a moving frame of reference and input 

{latex}$vec{\omega}^{\,}=\omega  \mathbf{\hat{k}}${latex}
