چکیده

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 which accounts for the effect of the rigid airfoil. Through numerical experiments it is found that the proposed methodology is sensitive to noise in the data. Modifications that circumvent this sensitivity are under consideration.

Simulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade

In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...

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...

Computation of Trailing Edge Noise with a Discontinuous Galerkin Method

Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Perturbation Equations (APE), which are employed as governing equations, are discretized via a Discontinuous Galerkin Method (DGM). Results are compared with theory and Finite Difference (FD) computations. Next to the radiated sound field, special attenti...

Unsteady RANS Simulation of High Reynolds Number Trailing Edge Flow

Unsteady vortex shedding at a trailing edge may cause pressure fluctuations and strong tonal noise which can have important consequences to the performance of marine and aeronautical type lifting surfaces. This paper presents data from unsteady RANS simulation of high Reynolds number trailing edge flow. It aims to identify and quantify dominant features of the trailing edge flow field over a tw...
