Interfaces and mixing: Nonequilibrium transport across the scales
Interfacial transport and mixing are nonequilibrium processes coupling kinetic to meso- and macroscopic dynamics. These processes play an essential role in fluids, plasmas, and materials, from celestial to atomic events. Addressing the societal challenges posed by alternative energy sources, efficient use of nonrenewable resources, and purification of water requires an improved understanding of the nonequilibrium dynamics, interfacial transport, and mixing. This special feature issue builds upon recent achievements in understanding interfacial transport and mixing using theoretical analysis, large-scale numerical simulations, laboratory experiments, and technology developments. It brings together works in fluid dynamics, plasmas, applied mathematics, chemistry, material science, geophysics, and astrophysics. This collection of papers explores the state of the art in areas of interfaces and nonequilibrium transport and suggests future research directions in the field.
