Where

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

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

Note the additional terms for the centripetal acceleration and Coriolis force in the Navier-Stokes equations. In Fluent, we'll turn on the additional terms for a moving frame of reference and input

{latex}$\vec{\omega}^{\,}= -2.22  \mathbf{\hat{k}}${latex}
