Several different cases are considered, when the incident plane wave is a fast acoustic, slow acoustic, entropy, or vorticity wave. Results show that 1) a critical angle of the wave incidence exists, beyond which the regular wave solution of the linear problem can not be realized, 2) strongest sound waves are generated behind the shock wave, if the incident wave strikes the shock wave at the critical angle, and 3) at large Mach numbers of the upstream flow, the sound amplification factor asymptotically increases as the Mach number squared, while at the critical incidence, it is increased as the Mach number cubed., 資料番号: AA0047427005, レポート番号: JAXA-SP-03-002}, pages = {23--28}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Abnormal amplification of sound waves refracted by an oblique shock wave}, volume = {JAXA-SP-03-002}, year = {2004} }
