Binary mixtures in linear convection arrays
WebDec 27, 2024 · For mixed binary or multi-component solutions, the surface tension will vary with temperature and concentration. When the temperature or concentration gradient occurs on the free surface of the binary solution, the surface tension gradient is generated, which drives the fluid to flow.
