LES tests on airfoil trailing edge serration
In the present study, a large number of acoustic simulations are carried out for a low noise airfoil with different Trailing Edge Serrations (TES). The Ffowcs Williams-Hawkings (FWH) acoustic analogy is used for noise prediction at trailing edge. The acoustic solver is running on the platform of our in-house incompressible flow solver EllipSys3D. The flow solution is first obtained from the Lar...
متن کاملComputation of trailing edge noise from an incompressible flow calculation
A new methodology for calculating low Mach number trailing edge noise is developed and tested. The input to this methodology is the fluctuating surface pressure obtained from an incompressible, turbulent flow calculation. The surface pressure is used to calculate an intermediate incident pressure. This pressure in conjunction with the sound-hard boundary condition yields the scattered pressure ...
متن کاملEmpirical study of flat plate trailing edge flow and noise
This paper presents results of an empirical study on the flow and noise generated by the trailing edge of a flat plate encountering low turbulence fluid flow. Simultaneous measurements of flow and far-field noise data have been taken in an anechoic wind tunnel at the University of Adelaide. Velocity data about the trailing edge and in the wake have been measured using hot-wire anemometry. These...

متن کاملLES of the trailing-edge flow and noise of a controlled-diffusion airfoil at high angle of attack
Large-eddy simulations (LES) of flow over a low-speed airfoil at high angle of attack (15◦) are performed using two different flow solvers, Fluent and CDP, on the same fine structured mesh, whose density was previously shown to provide a reasonably accurate trailing-edge flow for noise predictions at a lower incidence of 8◦. These simulations are compared with detailed pressure measurements mad...
