Only centrifugal force is utilized currently to drive gas-phase thermal convection in space. This paper presents an alternative way to drive thermal convection. From the investigation of combustion oscillation in rocket motors, a new thermal convection had been found in stationary acoustic fields. Analyzing the phenomena, acoustic radiation force is found to be the candidate driving force. With a simplified system using a hot wire as a cylindrical heat source, the characteristics of the convection in acoustic field are investigated experimentally. A numerical modeling that includes the radiation force succeeded in reproducing the convection. Knowledge for further application is obtained., 資料番号: AA0063349021}, pages = {80--83}, 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/ISAS)}, title = {微小重力場における音場を利用した熱対流の生成}, year = {2007} }
