Trailing edge noise theory for rotating blades in uniform flow [PDF]
, 2013 This paper presents a new formulation for trailing edge noise radiation from rotating blades based on an analytical solution of the convective wave equation. It accounts for distributed loading and the effect of mean flow and spanwise wavenumber.

Numerical analysis of noise characteristics of a contra-rotating axial fan
IOP Conference Series: Earth and Environmental Science, 2012 Numerical analysis of the flow-field in a contra-rotating fan has been performed by using the CFD method. The LES technique is applied to simulate the 3D unsteady whole flow-field of the fan. Several monitoring faces are specified in the flow-field between the two impellers.

How to improve open rotor aerodynamics at cruise and take-off [PDF]
, 2014 A key challenge in open rotor design is getting the optimum aerodynamics at both the cruise and take-off conditions. This is particularly difficult because the operation and the requirements of an open rotor are very different at cruise compared to ...
