A numerical study has been made on chaotic behaviors of forced convection in the transition regime. The microscopic turbulent flow in porous media is governed with the short-distance turbulent mixing due to the interstitial vortex in pore and the long-distance one around the solid. Judging from the examination on Lyapunov exponents, it is considered that the chaotic behaviors have a close relevance to the transition to turbulent flow. The relation between transport phenomena in porous media and chaotic behaviors of flow has been discussed.
