New technology for America`s electric power industry. Diagnosis and control of flow-induced tube vibration in heat exchangers and steam generators

Description

At present, it is not possible to predict the coupled tube/fluid interaction using the fundamental principles of fluid dynamics. Argonne has developed advances in applications of turbulent fluid flow theory to provide an alternate pathway for resolving practical tube wear problems. In Argonne`s approach, the fluid forces that act on tube arrays in cross-flow are measured. These forces result from the individual motions of the tubes within the tube array. From the fluid forces, fluid damping and stiffness are quantified with respect to their association with coupled tube motion. A characterization of the fluid flow state is then established, based ... continued below

From the fluid forces, fluid damping and stiffness are quantified with respect to their association with coupled tube motion. A characterization of the fluid flow state is then established, based on the measured motion-dependent fluid forces. Design guides and diagnosis techniques can subsequently be provided, based on the flow characterization profile.
