Abstract
Electrochemical measurements of mass transfer in a turbulent pipe flow are presented. In particular the effect of flow obstacles, such as orifices and circumferential slots with varying diameter and axial length, has been studied. The results also include measurements of mass transfer downstream, a sudden expansion or reduction of the tube diameter. The experiments were performed at a Schmidt number of 1460 and Reynolds numbers ranging between and . The work presented in this paper is a part of a project aiming to study the relation between corrosion and mass transfer at high flow rates with particular emphasis on disturbed turbulent pipe flow.
