Abstract
A method for performing aeroacoustic simulation, where the acoustic field is computed by the equations split from the flow field, is applied to the acoustic field of an object on the large flat surface. The acoustic field is obtained by the equations defined by the difference between the compressible and the incompressible flow equations. The acoustic equations are solved by the finite volume method with the fourth order WENO scheme. A rectangular cylinder with the limited width and an automobile rear-view mirror are calculated and the acoustic fields are investigated. The aspects in the near fields are different, while the emission patterns in the far fields are similar. The result of the rear-view mirror shows that the fluctuations of the regions with low acoustic density located downstream both outside and inside the mirror cause the acoustic emission.
