Method, system and apparatus for detecting defects in a honeycomb body using a particulate fluid

Abstract

A system, apparatus and method for detecting defects in a honeycomb body. The system and apparatus include a fixture adapted to hold the honeycomb body, a particulate fluid source, a pipe which defines a flow path between the particulate fluid source and a first end face of the honeycomb body thereby allowing particulate fluid to flow from the particulate fluid source to the first end face of the honeycomb body. The particulate fluid emerges at a second end face of the honeycomb body through defects, if any, in the honeycomb body where the positions of such defects may be monitored. The system and apparatus includes a flow straightener disposed in the flow path to minimize boundary layer influence of the pipe on the flow of the particulate fluid. A substantially uniform velocity flow profile is provided to the first end face of the honeycomb body.
