Leak-rate of seals: comparison of theory with experiment

TL;DR

This paper presents experimental measurements of rubber seal leak-rates and compares them with a new theoretical model based on percolation and contact mechanics, showing good agreement.

Contribution

It introduces a novel theoretical approach to predict seal leak-rates and validates it with experimental data.

Findings

Good agreement between theory and experiment

Theoretical model accurately predicts leak-rates

Enhanced understanding of seal leakage mechanisms

Abstract

Seals are extremely useful devices to prevent fluid leakage. We present experimental results for the leak-rate of rubber seals, and compare the results to a novel theory, which is based on percolation theory and a recently developed contact mechanics theory. We find good agreement between theory and experiment.
