Immiscible fluids flow in soils: numerical and experimental solution

Popis výsledku v původním jazyce

The increasing production and use of organic chemicals of the type non-aqueous phase liquid (NAPL) is a serious environmental problem due to leakage of surface and underground storage tanks and eventual disasters which form a hazard of contamination of soils and aquifers. The remediation processes taking place after the soil contamination. We are presenting a computational module - the PollutTransport Module for the analysis of NAPL transport in liquid and gas phase in the vadose zone, in soils unsaturated and saturated with water. The effect of the temperature is taken into account too, thus the heat flow is included. A solution of multiphase fluid and heat flow process posses two main problems: 1. Development of realistic and practical model for fluid constitutive equations; 2. Development of a procedure to solve the problem of multiphase flow governing equations. Main interest is in improvement of the definition of primary variables namely use of Primary Variable Switching Scheme (P
