Biofouling affects the performance of a tidal turbine blade primarily by increasing surface roughness, which leads to increased drag, reduced lift, and ultimately, decreased power output. Biofouling is the accumulation of microorganisms, plants, algae, and animals on submerged surfaces. Tidal turbine blades are particularly susceptible to biofouling because they are constantly immersed in seawater, which is rich in marine organisms. The accumulation of biofouling on the blade surface increases the surface roughness, disrupting the smooth flow of water over the blade. This increased roughness leads to increased drag, which is the force that opposes the motion of the blade. The increased drag ....
