Abstract
Mechanical behavior of particle-fluid system is widely related to various engineering problems such as boiling, piping and liquefaction in the field of geotechnical engineering. This study employed LAT (Laser-Aided Tomography) technique in permeability and boiling tests and proved it’s usefulness for visualizing grain-pore fluid interaction. During these tests, the local velocity profile was also obtained by PIV (Particle Image Velocimetry) analysis. As a result, the permeability coefficient measured in the tests was in good agreement with that estimated by Ergun’s equation. The interaction between grains and liquid monitored during boiling condition showed a high degree of locality and nonstationality.
