Abstract: The effect of oxidation on the stress-rupture behavior of fiber bundles was modeled. It is shown that oxidation-induced fiber strength degradation results in the delayed failure of the associated ...

Abstract: One of the key obstacles precluding the maturation and commercialization of planar solid oxide fuel cells has been the absence of a robust sealant. A computational model has been developed in ...

Abstract: In order to increase the efficiency of advanced microturbines, durable alloy foils are needed for their recuperators to operate at 650–700°C. Prior work has demonstrated that water vapor ...

Abstract: The Oak Ridge National Laboratory (ORNL) has been involved in research and development related to improved performance of recuperators for industrial gas turbines since about 1996, and in improving ...
