Training case study: Vibration concern in steam generator unit

May 12, 2025

A TEMA AES exchanger with carbon steel tubes produces 7.5 bar steam on the shell side with a weight fraction vapor of 0.3 at the shell exit (Figure 1). The operator has seen no evidence of tube damage in the operating unit, but the Xist vibration analysis flags fluidelastic instability (FEI)...
