抄録
内容記述 A method for computational aeroacoustics using the equations split into the incompressible flow part and the acoustic part is investigated in this paper. The equations derived based on Mach number expansion, and the method to solve them with high accuracy and stability are shown. The finite volume method using WENO scheme is applied to the acoustic field around a circular cylinder. Comparing the present method with the approximate solution based on the acoustic analogy, it is found that the acoustic field has been decayed according to the square root of the distance from the object further from about 10 times the diameter. In addition, 15 grid points per a wave length can give a sufficiently accurate solution by the present method.
