Labyrinth Seal Analysis. Volume 1. Development of a Navier-Stokes Analysis for Labyrinth Seals

Abstract

A technique has been developed to solve the Navier-Stokes equations for the flow in labyrinth seals. The technique utilizes a linearized block implicit-alternating direction implicit procedure to efficiently solve the unsteady governing equations to a steady state with appropriate boundary conditions and initial conditions. The resulting code was used to calculate the flow in a wide variety of labyrinth seal geometries under various flow conditions. Comparison with available experimental data indicates that the code will be a valuable tool in analytically evaluating the performance of existing and future labyrinth seals.
