Abstract:
The finite element method numerical simulation (COMSOL) is used to investigate the influent of parameter on salt-figuring phenomenon between homogeneous layers of solution. The results show that thermal Rayleigh numbers RT、salinity Rayleigh numbers RS and initial density stability ratio Rρ0 all influence the salt-figuring phenomenon. When both RT and Rρ0 increase, the salt-figuring pattern emerges more slowly, and the number of figuring shaped pattern increase. When the RS increase but Rρ0 decrease, the salt-figuring pattern emerges more quickly, and the number of figuring shaped pattern are also increased. In addition, there are phase transition of salt-figuring property while the RS is large enough. The study of multilayer salt-figuring phenomenon shows that the affection between adjacent interface are important to the shape and growth of salt-figuring.
