Experimental study on the application of boundary layer theory method to the estimation of soil solute transport parameters;

Simulation of one-dimensional solute transport in homogeneous and heterogeneous soils with scale-dependent fractional advection-dispersion equation;

The relationship between water table depth and saliniztion of soil has been studied by numerical simulation on the basis of theory of the soil water dynamic and solute transport in the Atmosphere Salinization of Soil Ground water Continuum(ASGC).

Based on the lab-experiments on the in-situ leaching processes of sandstonetype uranium deposit, the idea of front of solute migration and the specific front of solute migration was presented in this paper, and it will be a way to study the solute migration.

In order to study the convection velocity of multi-scale eddy structures in turbulent flow field with the background of high turbulent intensity and wide range of eddy scales, velocity measurements are carried out at different places on the center line of turbulent jet flow with circular nozzle with IFA300 double-channel anemometer and two hot-wire probes.

The convection velocity in the turbulent boundary layer plans an important role in describing the characteristics of transportation of the momentum, quality and energy in turbulence, serving as a bridge between spatial description and temporal description in the studying of turbulence, and Taylor’s frozen hypothesis that we often used is also related to the convection velocities for turbulence.
