Aeromechanics and Performance Simulation for Turbomachinery

Prediction of blade row performance and aeromechanics is important to turbomachinery development because turbomachinery blading lies at the heart of all types of turbomachines: pumps, fans, compressors, turbines etc. Improving the aerodynamic (or hydrodynamic) and structural aspects of the blading is essential to meeting modern requirements for performance and durability. If we consider that the fluid mechanics primarily influences performance, including fuel efficiency, then the structural mechanics is more responsible for durability. But of course, the two are closely related, and that is particularly true as the operating temperature increases, as in the hot section of modern gas turbines. Most end users do not want to sacrifice durability for energy efficiency, but rather demand both. Continue reading
