Which mechanism reduces the efficiency of a steam turbine operating with wet steam containing liquid phase water?

💡 Explanation

When wet steam containing liquid water impacts turbine blades, liquid droplet impingement erosion occurs because the water droplets accelerate and cause mechanical wear on the blade surface upon collision, reducing efficiency. Therefore erosion results, rather than increased thermal conductivity, reduced heat transfer or lubrication, which rely on other thermodynamic factors.
