Popis: An experimental study has been made of the chaotic behavior in the transition to turbulence of flow through porous media consisting of a bank of tubes in a narrow gap. Judging from the examination of the correlation dimension and the maximum Lyapunov exponents, we can identify the chaotic behavior in porous media for Re > ∼60. Rapid increase in the maximum Lyapunov exponents was observed for Re > ∼300. Also, the spatial distribution of the Lyapunov exponents is discussed.
