  • Stage found in the lab
  • Has relatively fine

adjustment

  • Need to fabricate base

plate to mount it securely to the isolation table

  • For flexibility of injection system to allow for needle to move chose brake

lines

  • Can withstand high pressures (3,000psi+)
  • Robust and cost effective

  • Approached Dr. Lam to discuss speaker dampening
  • Two really important points

○ Added noise in graphs due to lights ■ No way to get rid of that ■ Can implement a filter to reduce the noise ○ We should be wearing earplugs!! ■ Certain frequencies can be damaging to our ears ■ All feasibility testing was done wearing earplugs ■ This was really great advice

  • Ordered Materials
  • Developed designs

○ Redesigned 3 times ○ Discussed with Dr. Lam ○ Suggested a change in the internal pitch angle ○ 3 different fixtures for each ■ Creating one of each first for proof of concept ○ Rob - machining

  • Problems we ran into

○ Machine shop has dull tools ○ People spread out tools, don’t clean or put things in the wrong spot ○ Tried out two different machining methods ○ Had to construct fixture

  • The future

○ Bought sharp carbide inserts for lathe tools so future machining will go faster ○ Fixture constructed to make things easier

  • Glass Pipette and Keyence camera used for liquid supply and visuals
  • Needle was submerged in water
  • Various frequencies were attempted

○ 10 hz was visible to naked eye ○ Need more complex camera for higher frequencies ■ Current camera can only shoot 28 fps

  • End of semester (gate review)

○ Testing with at least three different gaskets ○ Marking glass tube to measure amplitude of

  • scillations

○ High speed camera ■ Current camera not fast enough to capture

  • scillations at high frequencies

■ Super resolution, low fps ○ Possibly different speaker orientations ■ One vertical, one horizontal ○ 6” speaker isn’t there yet; hopefully soon

Slide 32 12/10/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab

For the next three weeks, our team plans to complete the following tasks:

  • Testing the oscillating system with varying criteria
  • Collecting data and searching for dampening reasons
  • Gate review (Monday, 12/14?)
  • Enroll in MSD 2
  • Christmas, New Years
