Abstract
The dissolution process of the rock salt is actually a complicated process in fluid dynamics and chemical kinetics; therefore, the mathematical model for the solute-fluid flow during the cavern building may be established to research the change rule of the form of the cavern boundary based on the kinetic analysis of the convection–diffusion process, with integration of the basic theories of fluid mechanics and the principles of chemical kinetics. In order to research the dissolution mechanism of the rock salt under the condition of dynamic water, the method of numerical simulation has been employed to simulate and study the factors with effect on the fluid transport mechanism in solution mining cavern of the rock salt, and its dissolution in dynamic water has been simulated and researched. The result shows that the model established in this paper may well describe the dissolution process of rock salt under the condition of dynamic water, providing basic analyzing means for the research on the rock salt dissolution in dynamic water.
