A Coupling Scheme for Direct Numerical Simulations with an Acoustic Solver
Institut für Aerodynamik und Gasdynamik, Universität Stuttgart, Pfaffenwaldring 21, 70550 Stuttgart.
A code for direct numerical simulations (DNS) has been coupled with an acoustic solver for aeroacoustic applications. The DNS code is intended to compute the noise generation while the acoustic far-field is evaluated using the linearized Euler equations. Both codes run on different computers on which they show their best computational performance. As a test case, we show a pressure pulse emitting from the DNS domain and being propagated by the acoustic solver.
