Water droplet erosion

The emphasis of discrete water droplets serves to distinguish the WDE problem from liquid jet erosion and cavitation.

[2] Recently, Ibrahim & Medraj developed an analytical model to predict the threshold speed of water droplet erosion and verified it experimentally, a challenge having been attempted hitherto without success since the 1950s.

[3] For an extended period of time, many industries have encountered the problem of erosion due to water droplet impact, and it continues to reappear wherever rotation or movement of a component at high speed in a hydrometer environment is employed.

Recently, with the use of larger wind turbine blades, the issue of erosion of the leading edge due to rain droplets has grown more grave.

Aerodynamics efficiency of turbine blades is severely diminished due to leading-edge erosion, resulting in a considerable decrease in annual energy production.
