Turbine design

Definition

Turbine design refers to the engineering process of creating turbines that convert kinetic energy from fluids, such as water or air, into mechanical energy for power generation. Effective turbine design is crucial for maximizing energy conversion efficiency and involves considerations like blade shape, size, materials, and operational conditions. This impacts energy conversion systems and presents various challenges that engineers must address to enhance performance and durability.
