Theoretical research on sliding radial seals applicable to ship CP propellers

Abstract

Assumptions of a physical model, equations describing it, flow diagram of a relevant computer calculation program as well as results of the static calculations of the sliding radial seals usually applied in ship CP propeller systems are presented in the paper. The model takes into account the diathermic description of oil flow through the bearing interspace. The calculation results of an exemplary seal are compared with those obtained from a simpler, adiabatic oil flow model.
