Micro Bubble Generator (BG-1000)

Artikelnr: BG-1000

*Diese Seite ist leider nur in Englisch verfügbar.*

Generating the ideal seed particles for Wind Tunnel and Aerodynamics flows in Planar and Volumetric PIV

Produktdetails

The TSI BG-1000 surfactant/water based micro bubble generator (patent pending*) is designed to produce large amount of bubbles as seed particles for Particle Image Velocimetry (PIV) – planar and volumetric, for flow measurements in wind tunnels (opened or closed type) or open environment. The bubbles with mean diameter of 15 microns are excellent to follow the flow, around small structures or in boundary layer, to provide measurement with the highest accuracy and spatial resolution. The high concentration output of 107 bubbles/s and the long residence time make this generator the best generator for your flow applications.

The surfactant/water based bubbles with 15 micron mean size allow planar PIV measurement with field of view up to 1.5 m by 1.5 m and volumetric PIV with volume size of more than 6000 cm3, while having excellent fidelity to resolve small structures of the flow.

*Patent pending US 2011/0284648 A1

Two models of the micro Bubble generator are available – BG-1000 and BG-1000E. The two models have the identical features and benefits except the voltage input. The BG-1000 requires input voltage of 110V while the BG-1000E has the 220V power requirement. Close up image of the spherical shaped bubbles with high scattered intensity:

Applications

  • Wind tunnel flows
  • Airflows in large scale facilities
  • Turbulent boundary layers
  • Flows around airfoil or objects
  • Wake flows
  • Two phase flows

Leistungsmerkmale & Vorteile

  • Bubbles with size of 15μm and neutrally buoyant in air flow environment
  • Bubbles spherical in shape generating high intensity for large field of view or volume, at magnification of 0.025 or higher, without any glared point
  • Long residence time of more than 30 minutes, making long time duration measurements feasible
  • Short settling velocity of 0.18 mm/s giving the fidelity for the bubbles to follow flow even around small structures
  • High bubble output of more than 107 bubbles/s and high concentration of 20,000 bubbles/cc at the exit of nozzle, allowing the extraction of the smallest flow structure in your measurements
  • Non-toxics and non-stick on window surfaces due to the low viscosity of the surfactant/water mixture
  • Easy to operation with generator ready to be used in less than 5 minutes
  • Low Cost of operation and ownership with simple and easy maintenance procedure with no extra gas to purchase
