Impact/Purpose:

Journal Article

Description:

A simple model is presented that allows the pressure difference in a subslab aggregate layer to be estimated as a function of radial distance from the central suction point of an active subslab depressurization system by knowing the average size, thickness, porosity, and permeability of the aggregate along with total flow rate. The flow regimes may span the range from fully developed turbulence, through the transition, to Darcian flow.
