Modeling of ASTM A27 carbon steel hydraulic turbine runner degradation by synergistic effects of erosion-cavitation and corrosion under dynamic turbulent flow

In hydropower plants like any other plants, part failures normally contribute to high maintenance and repair costs; revenue lost due to downtime and cost of replacement power; decreased operating efficiencies; and reduction of equipment service life. In working conditions, the flow of water over the part has a great effect on the rate of corrosion. This means that the shape and condition of the parts in use will have a significant impact on their lifetime, as even a small scratch could cause affect how solution moves over the part, and therefore how it will corrode. In this project we propose a combined experimental and simulation study of the corrosion of materials that are directly used in hydroelectric applications. By mimicking the working environment of these materials, we will develop predictive corrosion models that will support Hydro-Québec in their technology development.
