INTRODUCTION Flow Loops Rotating Cylinder Rotating Cage Jet Impingement Annular Flow Abstract Generally, there are two reasons for conducting flow accelerated corrosion tests. The first is to make a comparison of material performance or corrosion control methods, such as corrosion...

... from Equation (4) is calculated by: (8) i lim ( H + ) d = k m F [ H + ] b where the mass transfer coefficient, k_m, is found from the rotating cylinder correlation ( Eisenberg 1954 ): (9) S h = k m d D = 0.0791 × R e 0.7 × S...

... rotating cylinder rig is described that allows multiple measurements of corrosion rates to be made under controlled fluid flow conditions in hydrocarbon fluids such as crude oils or synthetic mixtures up to 400°C (750°F) and 70 bar (1000 psi). The use of the rotating cylinder allows corrosion data...

... are conducted using rotating cylinder electrode (RCE) tests under moderate shear stress and limited test conditions. ^{12 , 13} The chemicals that perform well, providing protection against corrosion in these initial screening tests, undergo final evaluations in high temperature and high pressure...

...Well-Developed vs. Developing Flow The geometry for these (pipe flow, impinging jet and rotating cylinder) experiments can be selected to allow the boundary layers for momentum and mass transfer to develop independently. The hydrodynamic boundary layer represents the region near the surface...

... carbon steel in CO₂ environments. Two different flow geometries: rotating cylinder and pipe flow were studied simultaneously in the same electrolyte within a glass loop. The comparisons were carried out over a wide range of parameters: T=20-80°C, pH 4-6, P CO 2 = 0 − 1 bar...

... to effectively apply laboratory data to field operations based on carefully generated corrosion data. This phase encompassed correlation of single phase, aqueous, sweet corrosion of steel in turbulent pipe flow to steel corrosion in jet impingement and rotating cylinder tests.

... conditions that cause diffusion limitations. Methods for testing for velocity acceleration effects have generally employed either pump-around systems or rotating specimens. Pump-around systems present a difficult experimental challenge. The rotating cylinder approach is probably best suited for studying...
