Hatsopoulos Microfluids Laboratory (HML)


The Hatsopolous Microfluids laboratory (HML) was created within the Department of Mechanical Engineering as a center for research activities which focus on understanding the dynamics of fluid with microstructure and the emerging science of microfluidics. The Hatsopoulos Microfluids Laboratory (HML) ( consists of a single open-plan 6300 ft^2 laboratory that houses seven active and three emeritus faculty plus over 45 students and postdoctoral researchers. A broad overview of the principal research areas of faculty members within the laboratory is summarized below:

  • optical imaging of complex flows
  • rheology and dynamics of complex fluids
  • dynamics of thin films
  • flow stability
  • flow-structure interactions
  • flow in microfluidic devices and 'lab-on-a-chip' applications
  • biofluid mechanics and biorheology
  • Capillary phenomena and contact line dynamics

    Common gastropods such as snails crawl on a solid substrate by propagating muscular waves of shear stress on a viscoelastic mucus. Producing the mucus accounts for the largest component in the gastropod’s energy budget, ...

    A simple way to generate propulsion at low Reynolds number is to periodically oscillate a passive flexible filament. Here we present a macroscopic experimental investigation of such a propulsive mechanism. A robotic swimmer ...

    We describe the design and construction of a new microrheometer designed to facilitate the viscometric study of complex fluids with very small sample volumes (1-10 μl)and gaps of micrometer dimensions. The Flexure-based ...

    We investigate the concentration-dependence of the characteristic relaxation time of dilute polymer solutions in transient uniaxial elongational flow. A series of monodisperse polystyrene solutions of five different ...

    We provide an overview of transient extensional rheometry techniques for wheat flour doughs in which the deformation and material response is well defined. The behavior of a range of model doughs was explored with a ...
