The rotating cage has been one method widely used in the industry. Severe corrosion in some instances has been generated with this method. This method has been used to select corrosion inhibitors in a challenging 45-60 mol % carbon dioxide field where mesa type severe corrosion was experienced . The rotating cage is used to assess corrosion in different applications such as assessing corrosion in lead cooled nuclear reactors. The random vortex method has been used to assess this profile in earlier work. This work will be used along with boundary layer theory to arrive at design equations that calculate the shear stress profile in a rotating cage as a function of radius of the cage, angular velocity and distance along the coupon.
