Abstract:

A study of interfacial turbulence is necessary to elucidate the complex nature of transport properties across turbulent interfaces occurring in engineering problems, where the structure of the turbulence in the bulk phase is germane to interfacial conditions--hence transport properties--and facilitates a theoretical assessment of the problem. The structure in a single phase system which has already been assessed, can be considered as a special case of a two phase dynamic system where one phase is at rest. There are obvious similarities in the turbulence structure of both systems, but unlike previous authors who envisage isolated pieces of turbulence eddies as migrating into the interface from the bulk phase--which is not compatible with the concept of turbulence phenomena--Khan was able to provide a more plausible and realistic explanation of interfacial turbulence, and hence surface renewal. The author has formulated a theoretical assessment of the problem based on this model of turbulence structure.
