    Analytical expression for flow field over cavity derived

    Investigation of flow over cavity that is filled with a second immiscible fluid

    A surface cavity filled with a fluid over which a second immiscible fluid flows is one of the basic building blocks of a “smart interface”. Now researchers from the Institute for Nano- and Microfluidics have been able to derive an analytical expression describing the flow field along the surface. The expression is valid for arbitrary viscosity ratios between the two fluids.

    The Capillary Channel Flow experiment on the International Space Station

    Talk by Michael Dreyer (ZARM Bremen), February 5th, 2013

    Between January and March 2011 scientists from DLR, ZARM Bremen, NASA and the Portland State University conducted a Capillary Channel Flow experiment on the International Space Station. The purpose of this endeavor is to investigate the behaviour of capillary flow through open capillary channels in an environment of compensated gravity.

    Exhibition at karo 5 shows history of the institute Reaktortechnik at TU Darmstadt

    An exhibition shows the development of the institute “Reaktortechnik” (reactor engineering) at TU Darmstadt from its beginning in 1962. The exposition focuses on the reorientation of the institute's research in the years after the Chernobyl disaster and a further restructuring to the Department of Energy Systems and Technology in 2004. With the latter TU Darmstadt responded to the changes in society regarding nuclear power.

    How to control the wetting dynamics of droplets

    Dynamic wetting of electrolyte droplet without (left) and with (right) an applied electric potential. Freeze frame of molecular dynamics simulation.

    Early spreading of electrolyte drops can be controlled via an electric potential and electrolyte concentration

    The early spreading of a drop is speeded up by the electrostatic energy stored in the electric double layer near the solid-liquid interface, a study by scientists at the Center of Smart Interfaces found. The degree of speeding-up does not only depend on electric potential, but also on electrolyte concentration. The results of the research were published in Physical Review Letters.

    Presentation by Werner Zapka, XaarJet AB and Royal Institute of Technology Stockholm, Sweden

    With the advance of new types of inkjet printheads, new ‘functional’ ink formulations and increasing knowledge in the understanding and optimization of the drop formation process it was possible to develop inkjet printing into an important manufacturing technique in a number of industrial application areas.
