Abstract
A multiphase flow cylindrical model test system includes a loading structure, a multiphase flow displacement model bucket, a data acquisition and analysis system, a flexible seepage model bucket and a dynamic control system. A multi-parameter test method in the displacement process of pollutants in three-dimensional multi-field and multiphase media is reasonably configured based on the sequential and superimposed application requirements of heat and steam in the thermal enhanced soil vapor extraction process. The disclosure has the following effects: it can conduct array-type measurement of deformation of specimen during the thermal enhanced soil vapor extraction process, measure the temperature field, conductivity field, moisture field, matrix suction distribution, soil pressure distribution, pore water pressure distribution and pollutant discharge rate of the specimen during the test, and realize the flexible wall permeability triaxial test with bidirectional control of the water head and overcome the influence of the polluted liquid on the test equipment.
