摘要

A modification is made to the mass flow parameters used in the Pitt-Peters and Peters-He dynamic inflow models. This modification allows a stable transition through the vortex-ring state region, and ensures a convergence both to any specified inflow state (within the region) and to momentum theory (outside of the defined region). The modification is a function of the instantaneous total flow at the rotor disk, and thus can be used in dynamic simulations.
