| Research Abstract |
We have studied on the dynamics of the Marangoni convection and its mathematical modeling, which is induced by the concentration gradient of the surface active materials. As a result, We have clarified that the magnitude of the Marangoni convection roll around a camphor disk fixed at a water surface is nonlinearly dependent on the surfactant concentration added to the aqueous phase. We have also analyzed the convection structure inside the droplet based on the hydrodynamics, which is driven by the interfacial tension gradient induced by the chemical reaction inside it.
