ABSTRACT:
Temperature transducers are mounted on the outside surface of a containment system such as a pipe to detect thermal stratification and fluctuations thereof. The transducers are mounted in an arc lying in a plane perpendicular to the flow direction in the system at each of several positions separated along the flow direction. The data obtained by the temperature transducers is supplied to a computer for calculation of stress using transfer functions summing changes in both temperature and position over time. The stress due to abnormal thermal loads is combined with other stress on the system so that fatigue usage and fatigue crack growth can be calculated.
