On the abrasion in riverine streams relevant to marine energy converters*

Marine energy converters and structures in riverine streams are subjected to varying sediment loads, consisting of organic and inorganic materials of a wide range of sizes and densities, which can impact these structures at different relative angles and velocities. Abrasion can lead to substantial damage and reduced performance in the case of marine turbines. The quantitative characterization and understanding of material response to abrasion play a crucial role in developing new resilient materials and coatings for durable structures, thus extending the lifespan of marine energy converters. Here, we will briefly explore the relevant parameter space for assessing such material response and present the features of a basic facility that enables long and customized testing.
