It has been known that we can reduce this noise by spraying water into the jet. But this mechanism is not clarified. In this report, we carry out two-dimensional numerical simulations of interaction between water droplets and acoustic sound by the Finite Difference Lattice Boltzmann method. We also carry out the simulation for solid bodies for comparison. It is shown that some differences appear in the sound pressure fields between the two., 資料番号: AA0063742018, レポート番号: JAXA-SP-07-016}, pages = {113--118}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {液滴による空力騒音低減に関する研究}, volume = {JAXA-SP-07-016}, year = {2008} }
