156B Week 5

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Test tunnel skeleton built (walls, fan mount, honeycomb)

    • Ceiling with test holes fabricated for use in laminar testing (incense sticks) and speed measurement with anemometer probe

  • Honeycomb effectiveness testing done

  • Final tunnel material to be purchased at the end of this week pending finalized tunnel length decision

Accomplishments from Previous Week

• • Obtained honeycomb slabs (free samples)

  • Purchased fans (4) and created mount

  • Prepared tunnel (ceiling) for laminar/speed testing

  • Purchased Anemometer for speed measurement

  • Laminar testing

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Purchase acrylic (Thicker, 1/4") for final tunnel (Harry, Melissa)

  • Assemble final tunnel walls (Harry, Melissa)

  • Test wind speeds (Emilio, Elliott)

    • Possibly purchase new fans (Emilio, Elliott)

  • Cleanup and edit report draft (Elliott)

  • Test effects of mesh at downwind end (All)

  • Brainstorm most user-friendly way to input flies (All)

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Email 4/19/15

• • Excited to see test tunnel and pilot test fruit fly movement in tunnel

  • Lab has Arduino uno for use, do not purchase

Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

Comments made in person, 4/22/15

• • To test for laminar flow we could use incense stick

    • purchased and utilized

  • Check with Nick busan/Mark anderson for sensitive flow speed measurement tool

    • did not have, we purchased an anemometer

  • Putting fans in series will double pressure drop with same flow rate

  • Putting fans in parallel will increase flow rate, same pressure drop

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • N/A

Risks and Areas of Concern

• • Crude anemometer test on flow showed much lower flow speeds than anticipated.

    • Must do more testing

  • CO₂ flooding system implementation

Resources or Information Required but not Available

• • N/A

Schedule

• • Describe upcoming milestone

  • Update Gantt chart.
