Influence of the Structure of Fabric Filters on the Velocity and Stress Fields of Filtration Flows in Their Vicinity

Abstract

An experimental study of filtration flow through textile filters focuses on the area of contact between the filter and the flowing fluid. Optical and complementary techniques based on laser Doppler velocimetry and flow birefringence are applied to filtration, providing precise data for the fine structure of the local velocity and mechanical stress fields near the filters. The effects of the woven structures on the mechanical properties and performance of the filters are studied.
