Experimental and computational investigation of flow in catalytic monolith channels

Monolith optimization is necessary for maximum efficiency during catalytic combustion. This paper describes a study undertaken to investigate the flow in catalytic monolith channels. A super-scale model of a single passage in a ceramic catalyst monolith was constructed and studied using pure air as the working fluid. Combustion of a representative natural gas mixture at the catalyst surface was simulated by electrical heating of the channel walls. The flow-field was probed with hot wire anemometers and fine wire thermocouples to obtain velocity and temperature data. Concurrently, the PHOENICS CFD package was used to model the flow. Results confirmed the presence of secondary flows and illustrated the effects of channel shape. The results are discussed as to their relevance to the design of a monolithic combustor for gas turbine applications. 15 refs.
