| Research Abstract |
This study proposed a prediction method of corrosion in complex flow fields using numerical simulations and simple electrochemical measurements in l aboratory. First, the polarization curves, which give the properties of corrosion reaction, were modeled as a function of the wall shear stress on metal surface. Next, a prediction system of corrosion speed and location was developed using electrostatic simulation and the modeled polarization curves from numerically estimated wall shear stress of a target structure. The comparison between a prediction and an experimental result was carried out under a complex flow field in order to discuss the effectiveness of the developed system.
