Abstract

The uniform flow generated at moderate rotation speeds and ability to control mass transport rates to the cylindrical surface together with uniform current-and potential distributions make

Fluid flow effects on CO2 corrosion: a review of applications of rotating cage methodology

“…The bubble test is not included because it does not simulate the flow effects. In addition, the use of an RDE, which operates only under laminar flow (Walsh et al , 2017) and with low WSS (Papavinasam et al , 2007), is not suitable for studies of flow effects in the oil industry. Concerning electrochemical measurements, the RCE is one of the most cited in the literature as will be shown further (item 3.1) and includes the use of autoclaves, which simulates the reservoir conditions of high temperatures and pressures.…”

An Overview of Major Experimental Methods and Apparatus for Measuring and Investigating Erosion-Corrosion of Ferrous-Based Steels

“…The rotating disc/cylinder electrode system is widely used in the study of flow-accelerated corrosion (FAC) and erosion-corrosion since 1950 due to its relative low cost and convenient operation [44][45][46][47]. It is seen from Figure 2 that two forms of rotating disc/cylinder systems are adopted in erosion-corrosion studies [7,30,[48][49][50][51][52][53][54][55][56].…”

“…where ω is the rotation speed, r is the radius of the rotating cylinder, d is the diameter of the cylinder, υ is kinematic viscosity of the electrolyte, and ρ is the density of the electrolyte. More details on the hydrodynamic parameters and mass transport coefficient of the rotating disc/cylinder system can be reviewed from Walsh's work [45] which provides a summary of this technique used in various FAC and erosion-corrosion studies. The rotating disc/cylinder system can simulate an erosion-corrosion environment conveniently.…”

“…The most serious issue of the rotating disc/cylinder electrode system is the control of the sand concentration when corrosive slurry is introduced into the test cell. Although the overall weight percentage or volume percentage of the sand particles is a certain value in the whole test cell, the real sand concentration at different liquid levels would be dramatically different due to the inhomogeneous sand distribution in the test cell [45]. As the samples are fixed at a certain height, the real sand concentration at the corresponding liquid level would keep changing with the variation of the rotation speed.…”

A New High-Efficiency Experimental Design for Optimizing Various Flow Velocities Testing in Extremely Aggressive Formation Water

“…To narrow the research gap, in recent years, the technology of rotating cage, which normally provides controlled mass transfer in flow for electrode kinetic studies, has developed as a compact, hydrodynamic experimental method [18]. Moreover, the maximum flow velocity is limited owing to the reliability of the equipment.…”
