“Analysis of Spatial-Temporal Dynamics of Cool Flame Oscillation Phenomenon Occurred Around a Fuel Droplet Array by using Variational Auto-encoder”, Iemura K,, Saito M., Suganuma Y., Kikuchi M., Inatomi Y., Nomura H., Tanabe M., Proceedings of the Combustion Institute,

This paper reports the results of the computational part of the Japan-German colaborative research project on droplet array cool flame, “Phoenix-2”. Cool flame oscillation is analyzed by newly introduced VAE-POD method that combines mode decomposition with non-linear attractor reconstruction. Phasewise and modewise analysis clarified the mechanism of complex spatio-temporal oscillation of multi-phase multi-species reacting fluid.

Graduate students, K. Iemura, R. Saito, and Y. Takahata made presentation at COSPAR meeting held at 13-21, July, 2024.
