Subsoil decontamination with biological techniques: a bio-fluid dynamics problem

A subsoil cleanup technology is called bioventing: bacteria are used to biodegrade pollutants and air is injected to enhance their activity. In this paper a general mathematical model describing the physical phenomenon is presented. The model is based on the theory of fluid dynamics in porous media. A multi-component and multi-phase fluid is considered and the system of partial differential equations is coupled with a population bacteria equation.
