Selecting the Proper Ceramic Material for a Regenerator Experiencing Large Temperature Gradients.

Abstract

The objective of this study is to select the optimum ceramic material for a new engine regenerator. The regenerator will be designed for operation at two working temperatures, a compressed air temperature of about 250 C and an exhaust gas temperature of about 1100 C. Candidate ceramic materials considered were of two types: (1) ceramic materials analyzed for operating temperatures up to 1200 C; and (2) ceramic materials anlayzed for operating temperatures between 1200 C and 1400 C. A figure of merit (FOM) rating scheme was used to determine the most suitable ceramic material for the regenerator in terms of mechanical, thermal, fabricability and cost parameters. Also, an analysis was performed to determine the most appropriate regenerator passage geometry on an aero-thermodynamic basis.
