The inward pinch model for high-Z impurity ions in a toroidally rotating plasma (PHZ model) has been improved to take account of passing/trapped particles and centrifugal force effect. It is found that the PHZ pinch is large for the barely trapped particles and the pinch velocity increases with the rotation velocity as in the original model.
