| Abstract | The bubbling pressure of a porous medium is defined as the capillary pressure at which the non-wetting fluid is first continuous through the medium. It is very important soil parameter in characterizing a partially saturated flow. The purpose of this thesis is to study the effects of pertinent soil parameters and fluid properties on the bubbling pressure. A capillary tube model analogy was employed to develop an
equation representing the bubbling pressure as a function of soil parameters and properties of fluid. The soil parameters being considered were porosity, characteristic diameter of soil particle, and a
coefficient which is a function of the pore size distribution index. The fluid properties were surface tension and specific weight.
Experiments were conducted to verify the theoretical equation
and determine tile coefficient. The media were selected to have wide ranges of texture, porosity, grain size distribution and pore size distribution. The wetting fluid used was distilled water and nonwetting fluid was air. |
