Abstract

This paper presents a case history of the failure analysis, identification of the failure mechanism and ultimate remedy for a large heat exchanger which experienced a number of tube failures in service. The tube array was an in-line geometry with streamwise tubes connected by platen fins. A variety of tests were carried out including metallography, thermalhydraulic and structural dynamic finite element analysis, and a wind tunnel model study. The failure mechanism was identified as fluidelastic instability and stiffening the relative motion of the platens proved effective in preventing further failures.
