What is Turbine Blade - Definition - Thermal Engineering

Modern turbine blades often use nickel-based superalloys that incorporate chromium, cobalt, and rhenium. Steam turbine blades are not exposed to such high temperatures, but they must withstand an operation with two-phase fluid. High content of water droplets can cause the rapid impingement and erosion of the blades which occurs when condensed ...

Possible Dual Rotor Technology for Wind Turbines

Second, the large base of the blades actually disrupt the wind, causing a wake behind them which reduces the energy harvesting capacity of any downwind turbines. Hu says that a turbine in the slipstream of another “can lose 8 to 40 percent of its energy production, depending on conditions.” Their solution? Add a second, smaller rotor. “To try to solve these problems, we put a small rotor ...
