Our research is focused on studying the influence of the interfacial and complex wetting phenomena on the hydrodynamics, phase change, heat and mass transport in liquid films, rivulets and drops. We use smart substrate-fluid interfaces for controlling the transport processes, especially for heat and mass transfer enhancement. The smart interfaces include structured substrates, substrates with nanoporous coatings, deformable and soluble substrates. The smart interfaces modify the flow stability, influence the density of the three-phase contact lines, induce liquid imbibition and Marangoni convection.

Current Projects:

Wetting of deformable substrates

Simulation of wetting phenomena in inkjet printing

Simulation of film evaporation

Wetting of porous coatings

Complex wetting, deposition phenomena

Zero-gravity distillation

Simulation of drop impact and evaporation

Heat transfer of falling films

Discontinuous cleaning

Wetting of soluble polymer surfaces

Condensation on superamphiphobic surfaces
