Researchers developed novel microfluidic rheometers for precise fluid analysis. These devices enable direct measurement of wall shear stress and shear rate in microchannels without needing reference fluids.

Area of Science:

  • Microfluidics
  • Materials Science
  • Fluid Dynamics

Background:

  • Traditional viscometers often require reference fluids and complex data post-processing.
  • Microfluidic devices offer miniaturization and precise control over fluid behavior.

Purpose of the Study:

  • To design and fabricate novel micromachined capillary on chip rheometers.
  • To perform wall shear stress and shear rate measurements on silicon oil and ethanol-based nanofluids.
  • To introduce a microviscometer design that eliminates the need for reference fluids.

Main Methods:

  • Fabrication of silicon-Pyrex microchannels using anodic bonding.
  • Integration of local probes for direct pressure drop measurements within microchannels.
  • Utilization of microstripe electrodes for studying dielectrophoretic and electrorheological effects.
