Screw Rotors with Partial Length Contact.

Abstract

Tribology theory suggests manufacturing screw rotors with partial helical contact along the longitudinal axis of the intermeshing rotors may significantly influence their lubrication characteristics. This paper considers the theoretical effects of using this geometry feature for multiphase flow machines. Modelling of machines that include partial contact along with other relevant aspects such as oil port location, has further been investigated using ANSYS CFX and some results of these simulations are presented and discussed.
