Development for inversion simulation with Dusty Gas Model in gas phase of soil

Abstract

The present study developed inversion simulation with Dusty Gas Model for molecular diffusion coefficient, Knudsen diffusion coefficient and obstruction factors. Then column experiments for dry soil mixed Toyoura sand with Bentonite were carried out in the laboratory. These parameters were gotten by using the inversion simulation developed in this study. It was found that the parameter gotten by the inversion simulation were similar to values of data published in the previous paper. Furthermore we could find the dispersivity in gas phase of soil.
