文摘

Numerical method to evaluate the theoretical flow for a gear machine is presented. Machine displacing action described through a discretization of the fluid domain. A robust geometrical approach which is able to process unconventional gear profiles. Algorithm suitable to study new gear profiles for reduced fluid borne noise. For involute gears, the proposed approach adheres to known analytical formulas.
