    Notable Flow Facilities

  1. Truncated Icosahedron (“Soccer Ball”) Homogeneous and Isotropic Turbulence Chamber
    2.

    A 1-meter-diameter, 20-fan-driven truncated icosahedron turbulence chamber capable of generating homogeneous, isotropic turbulence in the center region (48 mm diameter) at a maximum Taylor microscale Reynolds number of Reλ=357, with minimal gravity effect.

  2. Cubic Homogeneous and Isotropic Turbulence Chamber
    3.

    0.4-meter length, 8-fan-driven, maximum Reλ=156


    Related Measurement Tools

  3. Holographic Dynamic Deflection-Imaging Charge Measurement (HDICM) Apparatus
    4.

    In-house built apparatus capable of measuring particle charge and particle diameter using in-line holography. Particles are non-destructively tested for size and charge by acquiring holograms of particles falling through an electric field.

  4. Particle Preperation Lab
    5.

    A fume hood containing an automatic siever (Gilson GA-8 Ultrasiever) with a full complement of particle sieves with opening ranging from 5-45 µm (in 5 µm increments) for sieving particle samples into narrow diameter ranges.

  5. Planar 4-Frame Particle Tracking Velocimetry (PTV)
    6.

    An in-house developed system which combines two PIV systems to track particles over four consecutive frames. This combines the small time between frames afforded by PIV cameras with a doubled tracking history. This technique improves tracking accuracy.

  6. Laser Doppler Velocimetry
    7.

    Dantec Dynamics, Flowlite 2D, laser probe has 160 mm working distance. Can measure time-resolved 2D velocity at a single point in the flow.
