<p>This paper presents the development of an instrumented channel for two-dimensional multiphase flow of<br /> automotive fuels in unsaturated soils. Flow experiments were performed using water or diesel in an eolian sand at residual<br /> water saturation, a particular case of multiphase flow. Aspects such as the visual monitoring of the infil...

<p>This technical note presents some preliminary results obtained with the use of hydrophobic and hydrophilic<br /> tensiometers to measure liquid pressures in three-phase systems (air-NAPL-water). The porous tips of the hydrophobic<br /> tensiometers underwent a surface treatment known as silanization. The silanized tensiometers demonstrated l...
