High-speed back lit images of burning droplet were obtained and time history of the droplet diameter was measured using image processing. Results showed that maximum velocity in oscillating flow is predominant for the burning rate constant, meaning that the classical quasi-steady assumption is not valid. Mechanism of this droplet combustion characteristic was discussed based on the ratio of characteristic time scales of flow oscillation and gas diffusion., 資料番号: AA0063706039}, pages = {166--169}, 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 = {微小重力環境を利用した高圧下における液滴火炎の流速変動への応答に関する研究}, year = {2008} }
