To clarify the sound wave generation mechanism from a film heater, a very short heat pulse, width 2.5 micro-sec, was applied to the fluid, and the double-peak signal has been observed, indicating the generation of the sound by thermal process in the supercritical fluid, piston effect., 共催: 日本学術会議, Meeting sponsors: The Science Council of Japan, The Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA), 資料番号: AA0064113055}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {超臨界流体における高速な断熱過程の研究}, volume = {22}, year = {2006} }
