A Study on Mass Transfer Measurement in Piping Elements

Abstract

The mass transfer coefficient, which is related to the flow characteristics within pipe elements, is one of the important parameters to predict the pipe-wall thinning due to flow-accelerated corrosion. In this study, we evaluate the measurement uncertainty of the calcium sulfate dissolution method, which is a method for measuring mass transfer coefficients, to clarify the mass transfer characteristics of pipe elements such as elbows and T-shaped pipes. The relationship between the flow and mass transfer characteristics is also considered based on the results of mass transfer experiments on various piping elements.
