Abstract:

The development of reliable, efficient and low noise engine is an unremitting pursuit of aviation industry. Turbine is one of the core components of aero-engine, and its flow and heat transfer are always the top issues throughout the design and manufacture. As the noise from the engine fan and jet has been greatly controlled, turbine noise has become more important and has gained extensive concerns. To stimulate the industrial usage of proposed numerical methods in turbine simulations, numerical methods and investigations of the complex turbulence flow, heat transfer and noise in aero-engine turbines are reviewed. Firstly, focus is placed on the state-of-art of flow and heat transfer simulation in rotating cavities and rotating blades. Secondly, the research status of aeroengine turbine noise is analyzed, and the numerical methods of noise prediction are reviewed. Based on this, suggestions on further development of numerical methods and specialized software for the simulation of turbine flow, heat transfer and noise are proposed.

Key words: turbine, flow and heat transfer, aerodynamic noise, numerical simulation
