Enclosure Design for Brake Wear Particle Measurement Using Computational Fluid Dynamics

The harmfulness of fine dust generated by automobile brakes to the environment has recently received attention. Therefore, we aimed analyze and regulate brake wear particles in dynamometers. To accurately measure number particle mass, sampling system used needs minimize transportation losses reduce residence time enclosure system. measurement currently can estimate main loss but cannot evaluate complex flow field under different design conditions. We computational fluid dynamics (CFD) technology predict behavior static pressure characteristics, uniformity flow, In addition, compared basic structure system, combined with four factors affecting dynamometer, As a result, proposed that cross section dynamometer should be circular, outlet angle 15°, caliper fixed 150°, two sets splitters added. This improves reduces
