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
  • Development of optical measurement techniques for the simultaneous recording of speed and scalar variables (e.g. temperature)
  • Optimization of flow control in microfluidic fuel cells to increase fuel utilization and efficiency

Range of services

  • Experimental and numerical investigation of microfluidic systems based on surface acoustic waves
  • Design and optimization of flow control systems using surface acoustic waves
  • Non-contact temperature and three-dimensional velocity measurement in microchannels
