Laboratory of Groundwater and Mass Transport

Research Subjects

The researches in this laboratory have been concerned with terrestrial and environmental problems. Transport phenomena of contaminants with groundwater are closely connected with geological structure. We have studied them through several approaches based on multi-phase fluid mechanics.

Mass transport in porous media and complex flow channels

Solute dispersion in natural flow channels such as rock cracks or gaps in soils is related to resource and environmental engineering as mineral resources extraction or pollutant dispersion in underground. In general, natural flow channels have a complicated shape and the solute dispersion in these channels is affected by geometric characteristics of the channel. We examine the effect of channel geometry on the transport of soluble substances and to understand the dispersion process in irregular-shaped micro-channels. (Prof. Harada)

Non-invasive measurement on behaviors of solid-fluid mixtures

A non-invasive measurement system of kinematic nature of solid-fluid mixtures are developed. We applied the measurement system to various multiphase flows with solid particles.(Prof. Harada)
