| Outline of Final Research Achievements |
The objective of this research is to conduct an experimental study and to develop numerical methods for Darcy/Navier-Stokes coupled flow, which means the flow including the well-know Darcy flow in porous media and the fluid flow in a domain purely occupied with a fluid, such as water. The achievement of the above-mentioned research is as follows: The PIV measurement of the Darcy/Navier-Stokes coupled flow was realized through laboratory experimentation, and a new numerical method for the flow, based on the variational multiscale method, was developed.

本研究課題の学術的意義は，研究対象となるDarcy／NS連成流れに関する実験研究の希少さにある．現在に至るまで，Darcy／NS連成流れの実験研究は，非常に少なく，希少な実験を基にDarcy／NS連成流れに関する理論的考察がこれまで行われてきた．そのため，現在においてもDarcy／NS連成流れの実験研究は萌芽期にある．本研究成果は，この課題に対して貴重な実験結果を提供するとともに，Darcy／NS連成流れの予測手段を飛躍的に発展させたものとなった．
