Coherence measurement for early contact detection between two components

Abstract

In process and power plants, there are several structural components which may come in contact with the neighbouring components over a period of time. For example, the coaxial tubes often used for conveying hot fluids, where the detection of contact between the tubes at an early stage is important for safety and performance considerations. The paper presents the observation on the coherence behaviour for the detection of early contact based on the simple laboratory experiments. © 2005 Elsevier Ltd. All rights reserved
