Fan Aero Acoustic
An Acoustic Intensity Based far Field Prediction Method (AIBM) has been developed by Professor Mei Zhuang. This method coupled with associated computational Fluid Dynamics predicts the rotational field for a ducted fan or an open rotor. It has been well correlated with experimental data and is very effective in assessing rotor configuration (blade designs, blade numbers, etc.) as well as rotor installations.
Pioneering work is always being performed on acoustic liner optimization for acoustic inlets.
