| Outline of Final Research Achievements |
Effect of space scale on Marangoni convection was numerically investigated by using both of Molecular Dynamics (MD) and Computational Fluid Dynamics (CFD). Both the CFD and MD simulations show that four vortices were developed after deformation of the liquid film. Solutes were transferred along the liquid-gas interfaces by solutal Marangoni convection. The results of the CFD simulations qualitatively agree with that of the MD simulations. However, there are quantitative differences in terms of the maximum velocity in the liquid film and deformation rate and width of the liquid film. Numerical model by using S-CLSVOF method and considering Langevin equation was developed to expand CFD to nano-scale calculation.
