Presentation Transcript

  1. AAE 33l Fluid Mechanics Laboratory Hydrogen Bubble Wire V=0 to 100 volts I = 0 to .5 amp Electrolysis of Water Forms Hydrogen Bubbles on Small Diameter Wire Frame Water must be conductive Hard water (Lafayette) is conductive but calcium deposits on wire Can add Sodium Sulfate to adjust the conductivity Bubble Wire (~.001” dia.) Platinum – expensive &weak Tungsten – high strength Steel – stainless does not corrode Aluminum - weak Electrode (somewhere in flow tank) Lighting is Critical – Forward Scatter when possible

  2. AAE 33l Fluid Mechanics Laboratory Hydrogen Bubble Method Can form either Hydrogen or Oxygen Bubbles Hydrogen Bubbles – smaller less buoyant harder to see Oxygen Bubbles – larger more buoyant easier to see

  3. AAE 33l Fluid Mechanics Laboratory Pulse Wire – Measure Velocity
