Dynamical system theory conveys striking and uncovering information for clarifying dynamic properties of irregular temporal behaviors obtained in a broad spectrum of experiments and numerical simulations in the fields of mechanical and chemical engineering. It widely covers from the quantification of many important invariants such as Lyapunov exponent, fractal dimension and entropies, which yields a physical description of the dynamical structure, to practical applications such as nonlinear forecasting.

Our group is headed by Dr. Hiroshi Gotoda, and devoted to the experimental and numerical study on nonlinear dynamics of thermal fluid with rapid chemical reaction, in particular combustion and flame (e.g., combustion instabilities in land-based gas-turbine engine, aircraft engine, and rocket engine combustors, buoyancy-induced turbulent fire, and flame front instability in inverted gravity) from a viewpoint of dynamical systems theory.
