As a first step, we have examined its performance by computing traveling sinusoidal waves. Then, we found that the hybrid methodology achieves higher accuracy than the Euler computation when combined with a fifth-order WENO (Weighted Essentially Non-Oscillatory) scheme. Based on this knowledge, we have conducted both of fully third-order Euler/LEE and third-order-Euler/fifth-order-LEE hybrid computations. According to the results, the computed acoustic field is mainly composed of three waves having distinct frequencies: a high frequency wave (0.5 Hz) which seems to be caused by interferences from the wall, a medium frequency wave (2.2 Hz) corresponding to first-mode eigenfrequency of the jet exit geometry, and a low frequency wave (10 Hz). The computed pressure values are rather different between the two results, although these frequencies are not so much. This fact implies that the more we extend the region of fifth-order computation, the more the computed pressure values approach to physically correct ones in quantitative view.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
