Increasing miniaturization is already the subject of current research in chemical, biological and pharmaceutical process engineering. The reduction in the size of fluidic structures causes a shift in the dominant forces away from bulk forces and inertia to surface forces. As a result, completely new physical effects can be exploited.

Main research topics

  • Experimental investigations of flow influence by means of surface acoustic waves
