In relation to the time-scale of chemical kinetics, diffusive transport in micro-devices is faster than in conventional mixers. To exploit the resulting potential for chemical process engineering,â€¦ (More)

The focus of this contribution is on numerical simulation of processes with moving deformable interfaces involving soluble surfactants. Resolution of the interface is based on the Volume-of-Fluidâ€¦ (More)

The presence of surfactants, ubiquitous at most fluid/liquid interfaces, has a pronounced effect on the surface tension, hence on the stress balance at the phase boundary: local variations of theâ€¦ (More)

We present a computational approach based on the Volume-of-Fluid (VOF) method for simulating the influence of a soluble surfactant on the behavior of two-phase systems with deformable interface. Ourâ€¦ (More)

Let X be a real Banach space, J = [0, a] âŠ‚ IR, A : D(A) âŠ‚ X â†’ 2 \ âˆ… an m-accretive operator and f : J Ã— X â†’ X continuous. In this paper we obtain necessary and sufficient conditions for weak positiveâ€¦ (More)

We consider a coupled system of Navier-Stokes and Nernst-Planck equations, describing the evolution of the velocity and the concentration fields of dissolved constituents in an electrolyte solution.â€¦ (More)

By definition, mixing in chemical reactors is a multi-scale process since it aims at reducing the length scale on which the chemical components are segregated. Only this way, micro-mixing can beâ€¦ (More)
