RELATIONSHIPS BETWEEN ROTATING-DISK CORROSION MEASUREMENTS AND CORROSION IN PIPE-FLOW

The relationship of corrosion in a rotating disk system to that in a turbulent pipe flow system was examined. Closed-form, mathematical models that allowed prediction of the uniform corrosion rate in turbulent pipe flow based on rotating disk experiments were developed. A model for prediction of product film formation in turbulent pipe flow given the conditions under which a product film forms during disk flow also was developed. Practicality of the resultant models was demonstrated by comparing the model predictions to literature data. Model predictions were in good agreement with experimental results of other researchers.
