Test stand for measurement and sampling of brake wear particle emissions

The thesis deals with the practical design of an airtight enclosure around the braking mechanism with the filtered air has drawn into the chamber and provides cooling to the braking mechanism. This flow scavenges the wear particle produced by brake wear. The air is drawn into the designed pipe system with dilution tunnel and multiple sampling points for the isokinetic sampling process, then it is directed to the exhaust system by a variable speed centrifugal fan. This thesis includes the literature survey, description of two different design variants with pressure drop calculations, technical drawings and part lists.The thesis deals with the practical design of an airtight enclosure around the braking mechanism with the filtered air has drawn into the chamber and provides cooling to the braking mechanism.
