| Research Abstract |
THE PRESSURE-PLATE AND THE GRAVITY DRAINAGE COLUMN EXPERIMENTS WERE TESTED TO CONFIRM THE EFFICIENCY OF THE EMPIRICAL EQUATIONS EXPLAINING THE WATER-NAPL-AIR THREE-PHASE CAPILLARY PRESSURE-SATURATION RELATIONSHIPS. THE PRESSURE-PLATE EXPERIMENTS SHOWED THAT WATER SATURATION IS IDENTICAL TO THE WATER RETENTION CHARACTERISTICS OF AIR-WATER TWO-PHASE CONDITION. ON THE OTHER HANDS, THE GRAVITY DRAINAGE COLUMN EXPERIMENTS SHOWED THAT TOTAL LIQUID SATURATION UNDER THREE-PHASE CONDITION WAS NOT AGREEMENT WITH THE OIL RETENTION CHARACTERISTICS OF AIR-OIL TWO-PHASE CONDITION, WHEN OIL THICKNESS WAS THIN. ON THE OTHER HANDS, ANEW DEVICE WHICH CAN DETERMINE THE UNSATURATED WATER. OIL AND AIR CONDUCTIVITY DIRECTRY WILL BE DEVELOPED IN THE NEAR FUTURE USING DISPERSION COLUMN DEVICES.
