RISIn-Plane Fluidelastic Instability Evaluation of Triangular Array Tube Bundle Using Fluid Force Measured Under Steam–Water Two-Phase Flow Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, tube-to-tube wear indications of triangular tube bundle steam generators (SGs) caused by fluidelastic instability (FEI) in the in-plane direction of U-bend region (in-plane FEI) have been reported. Several ...
Investigation of In-Plane Fluid Elastic Instability for a Triangular Tube Bundle Subjected to Two-Phase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, in a newly installed replacement steam generator, in-plane (IP) fluid elastic instability (FEI) for the heat transfer tubes has occurred. The fluid elastic instability is one of the severe vibrations in ...
