A02

Project A02 focusses on the Generic Configuration Droplet, with which dynamic processes in droplet coalescence, droplet propagation and droplet break-up are investigated with high temporal and spatial resolution. Fluids with shear rate-dependent viscosity or viscoelastic properties as well as mixtures are analysed. The range of substrates also includes swellable surfaces and surfaces coated with nanostructures as well as those with pattern-like wetting and dewetting properties. Charge effects on droplets are also being investigated. The influence of heat transfer on the coalescence and break-up behaviour is studied by applying temperature gradients.
