This paper describes a mathematical model and adaptive numerical simulation of the time-dependent multiphase, multicomponent flow which occurs when a gas venting process is used to remove a volatile contaminant from a porous medium. The numerical simulation is adaptive in both space and time and involves the use of a finite element spatial discretization method incorporated within the SPRINT2D PDE software ([1]). 1 Introduction An important environmental problem faced in a number of industrial sectors today is that of how to deal with the contamination of soil and groundwater due to spills or seepage of unwanted substances, such as chemical waste or hydrocarbons for example. Frequently these contaminants are volatile and will evaporate freely given a sufficient supply of unsaturated air. In such situations a popular clean-up technique is to employ a venting process which extracts the contaminant-rich gas phase by means of vacuum aspiration of the ground in the vicinity of the spill. ... |
