Would you like to rotate the fluid with respect to the axis of the pipe?

CFD is a tool which can be used to predict the dynamics of fluid based on what kind of boundary conditions we apply.

Radial Pressure difference and wall friction can induce the rotation of fluid particles/lumped fluid too. Viscous effect of fluid particles is also a major cause.

Give it an angular velocity

Ahmad K. Sleiti

Besides the angular velocity, you may impose rotation using source term (UDF) depending on what kind of rotation you need.
