Bodenluftstroemung in teilgesaettigten Boeden

Macroscopic flow equations for the multiphase flow in soils were derived in a deductive way from the microscopic Navier-Stokes equation for laminar flows. Physical assumptions were experimentally tested, and parameters of the multiphase flow were determined. Soil parameters were determined for six different soils. Unsaturated permeabilities for air and water could be described using the models by Brooks and Corey. It is demonstrated that the soil air flow can be treated as an isothermal process. An empirical relation was established for determining soil permeabilities from sieve curves. Pore fluid flow could be modeled using a non-linear statement.
