Abstract

Heat exchangers have been among the most troublesome components of both nuclear power and chemical process plants. Heat exchanger tubes are supported at intermediate points by support plates. Flow- induced vibration of tube can cause it to impact or rub against a support plate or against adjacent tubes and can result in tube fretting wear. Simulation of heat exchanger tube/ support dynamic interaction is presented. The tube/ support interaction parameters, ‘RMS Impact force’ and ‘Contact ratio’ are studied. These are significant inputs to predict fretting wear limited life of the heat exchanger tubes. An algorithm includes equilibrium iteration and variable time stepping based on convergence criteria is implemented in an in-house finite element program. The tool is validated solving documented premature failure case of shell and tube type heat exchanger.
