I am currently reviewing a research paper presenting an electrochemical study on corrosion-enhanced erosion. It attempts to link the CFD of a modeled flow to the corrosion rates of an elbow made of high-strength steel, is this possible?
Yes - Its possible I guess. There is a separate module named corrosion module in the latest release of COMSOL Multiphysics 4.4.

With a CFD model, you can calculate the fluid speed, and other magnitudes as temperature, pressure, concentration of chemical products. With this parameters you can calculate the wear rate. But there is specific software that do that, as comsy, or other from EPRI, so it could be more productive and efficient to use them.
Thank you very much for your inputs. I am wondering if a CFD software takes into account the metallurgy of the material by which the distribution of electrochemical potentials (and therefore, the electrochemical currents) can be calculated onto the meshed solid structure.
COMSOL would give you options to incorporate surface reactions or electrochemistry in your flow model. But I am wondering how much the fluid flow will affect the corrosion rate. Sometimes, solving a Navier-stoke equation for the flow is not really necessary and instead you could focus on the corrosion part.
