Simulation of CAA Benchmark Problems Using High-Order Spectral Difference Method and Perfectly Matched Layers
نویسندگان
چکیده
The high-order spectral difference (SD) method is used for the numerical simulation of several benchmark problems in computational aeroacoustics (CAA) to assess its effectiveness. A Perfectly Matched Layer (PML) absorbing boundary condition is implemented in the SD solver to minimize artificial wave reflections at computational boundaries. The performance of PML is tested and compared with the characteristic boundary condition. The numerical solution of Problem 1 “single airfoil response of impinging gust” in Category 3 and Problem 2 “trailing edge noise problem” in Category 4 of the Fourth Computational Aeroacoustics (CAA) Workshop on Benchmark Problems are presented here.

متن کاملAn optimized spectral difference scheme for CAA problems
In the implementation of spectral difference (SD) method, the conserved variables at the flux points are calculated from the solution points using extrapolation or interpolation schemes. The errors incurred in using extrapolation and interpolation would result in instability. On the other hand, the difference between the left and right conserved variables at the edge interface will induce dissi...

In the context of the numerical simulation of seismic wave propagation, the perfectly matched layer (PML) absorbing boundary condition has proven to be efficient to absorb surface waves as well as body waves with non grazing incidence. But unfortunately the classical discrete PML generates spurious modes traveling and growing along the absorbing layers in the case of waves impinging the boundar...
متن کاملAn Efficient Time-Domain Perfectly Matched Layers Formulation for Elastodynamics on Spherical Domains
Many practical applications require the analysis of elastic wave propagation in a homogeneous isotropic media in an unbounded domain. One widely used approach for truncating the infinite domain is the socalled method of Perfectly Matched Layers (PMLs). Most existing PML formulations are developed for finite difference methods based on the first-order velocity-stress form of the elastic equation...
