Dynamic behavior of temperature field in a buoyancy-driven turbulent fire

Publication date: Available online 5 September 2018Source: Physics Letters AAuthor(s): Kazushi Takagi, Hiroshi Gotoda, Isao T. Tokuda, Takaya MiyanoAbstractWe study the dynamic behavior of temperature field in a buoyancy-driven turbulent fire from the viewpoints of symbolic dynamics, complex networks, and statistical complexity. The permutation entropy and the horizontal visibility network entropy allow us to capture the subtle changes in temperature fluctuations. The possible existence of deterministic chaos in temperature fluctuations, as well as in streamwise flow velocity fluctuations Takagi et al. (2017) [6], is clearly verified using the multiscale complexity-entropy causality plane.
