Abstract

Avoidance of flow-induced resonance is crucial in managing the failure risk of industrial temperature measurements. To this end, we find that modal analysis of thermowell installations using traditional shell and beam theory, may offer a useful screening tool for at risk installations. This is demonstrated in part by a comparison of predicted resonances of flange-mounted thermowells with those described in reported flow tests.
