APPLICATION OF HYBRID CFD/CAA TECHNIQUE FOR MODELING PRESSURE FLUCTUATIONS IN TRANSONIC FLOWS

TASK Quarterly, 2013
Solving AeroAcoustics (CAA) problems by means of the Direct Numerical Simulation (DNS) or even the Large Eddy Simulation (LES) for a large computational domain is very time consuming and cannot be applied widely for engineering purposes.

Numerical Simulation of Aerodynamic Noise Generated by Large Wind Blade Airfoil

Kongzhi Yu Xinxi Jishu, 2017
Aiming to reduce aerodynamic noise of wind blade, a method of coupling CFD/CAA was used to simulate the aerodynamic noise of wind blade airfoil. In this paper, surface pressure distribution of airfoil was obtained by using STAR-CCM+ and the near sound ...
