Summary on Grant Application Form
Interfacial instabilities in evaporating systems arise in a diverse range of technological applications. Deformable surfaces involving a potential gradient are formed in many of these processes and a large variety of instabilities are known to occur. These include the Marangoni-Benard instability, effect, the Rayleigh-Taylor instability, the Kelvin-Lapace instability and vapour recoil instabilities. The role of the non-equilibrium properties of the fluid at the interface is of primary importance in determining the onset of convective structures at the interface. In a previous investigation by the applicants of a evaporating meniscuc for a single component system, the contact angle and the evaporation flux has been shown to determine the threshold of the onset of surface convection. These results are now to be extended in this work to multicomponent systems. Previous contact between the groups under the Convention and Interfacial Mass Exchange (CIMEX) European Research Network has identified the need for a combined theoretical, experimental and numerical study of interfacial instabilities in multicomponent systems. The objective of this collaboration is to develop new models for understanding and predicting the onset of interfacial instabilities in multicomponent evaporating systems. This research will combine the complementary experimental, theoretical and numerical expertise of the British and French groups. Novel experimental techniques have been developed by the French team to investigate and enhance transport Phenomena in evaporating systems. The British team has expertise in visualisation of high-speed flows and in numerical simulation of fluid interfaces.
