This paper describes a one-dimensional model that predicts the minimum static pressure in a rotating transfer passage taking into account both the centrifugal and the viscous forces, the latter having been neglected in previous studies. The minimum pressure is important as it determines the engine lubricating capacity and whether aero-cavitation may occur in the passage. The flow is considered laminar and the fluid is incompressible and Newtonian with constant viscosity. The current model predicts a lower minimum pressure within the transfer passage due to the inclusion of the viscous forces in the model.
