DEVELOPMENT OF LAT-PIV VISUALIZATION TECHNIQUE FOR PARTICLE-FLUID SYSTEM
Mechanical behavior of particle-fluid systems is extensively studied in various engineering field such as geotechnical engineering, mechanical engineering and powder technology. Although observation of complicated behaviors including interaction between particles and pore fluid is essential, very few efficient techniques are available for this purpose. From this point of view an observation technique based on LAT (Laser-Aided Tomography) and PIV (Particle Image Velocimetry) was developed and applied to the permeability experiments involving a seepage failure. The LAT-PIV technique enables us to visualize not only the particle motion but also the pore fluid motion and evaluate them quantitatively.
