Integrated System Build & Test
The Deliverable of P16371 MSD TeamIt's expected that this MSD team designs and constructs a device that is capable of meeting the customer requirements as outlined in the problem definition. Specifically, this means that the device must create a stable liquid meniscus, oscillate the meniscus at a frequency of approximately 100 Hz, be capable of utilizing multiple different working fluids, be able to interface with the other subsystems, and it must be reliable. In order to fulfill the customer requirements, it's also expected that the MSD team designs a computer program that allows for adequate control of the device. Therefore, upon completion of MSD II the customer will receive a device that meets his requirements along with a program that is capable of supplying the necessary controls. It's the customer's desire that the device which is being designed and constructed by this MSD team will enable him to conduct his doctoral research.
Team Vision for Integrated System Build & Test Phase
Anticipated TasksFor the integrated system build and test phase, our team expected to accomplish the following tasks:
- Purchase items necessary for final system, including a stainless steel syringe, LED light source, and amplifier.
- Continue designing final system.
- Perform necessary testing to validate engineering requirements.
- Modify Gantt chart as appropriate.
- Begin developing LabVIEW controls.
- Consult LabVIEW experts as necessary.
- Troubleshoot PID controls.
- Begin integrating the heater subsystem.
- Gain super powers.
- Eat lots of baked goods. It's expected that cookies are the impetus for superhuman powers.
- Begin cycling in the progressively warmer weather.
Accomplished TasksThe following tasks were actually accomplished during the integrated system build and test phase:
- Determined that a stainless steel syringe, LED light source, and amplifier are not necessary purchases. The system is fully and adequately operational without these items.
- Designed final fixture.
- Fabricated final fixture.
- Began development of LabVIEW controls.
- Integrated remote control capabilities for the stage.
- Eliminated issue with air bubbles in the system.
- Verified operation of the capacitance sensor with oscillations.
- Received approval for the ICNMM paper.
- Revised the Gantt Chart as appropriate.
- Fixed the clock in the lab.
- Celebrated St. Patrick's Day with soda bread. Yum!
- Dreamed about purchasing a beautiful, new BMW.
Imagine RIT Project Description
Dancing Bubbles Used to Study Boiling Systems
Have you ever seen water dance to Taylor Swift? Or rock out to Crazy Train? Visit our exhibit to see what we’re talking about and have fun blowing some bubbles. Our amazing senior design team will ‘boil down’ our Multidisciplinary Senior Design project and leave you feeling ‘cool.’ Boiling systems, such as a boiling pot of water, are incredibly effective at removing vast amounts of heat from a surface. For example, bubbles dissipate heat from the bottom of the pot of boiling water via bubble nucleation. However, boiling is a complex and chaotic phenomenon, and the fundamental physics are not well understood. If a greater understanding of bubble nucleation can be acquired, then more efficient designs for applications such as jet engines, computer chips, and nuclear plants can be developed. For this reason, the RIT Thermal Analysis, Microfluidics, and Fuel Cell Laboratory has proposed a system that is capable of studying the basic fundamentals of boiling. Our Multidisciplinary Senior Design team was tasked with designing and fabricating a device that is capable of conducting such an investigation. In order to study boiling fundamentals, our device was required to create a stable liquid meniscus, control the liquid volume of the meniscus under varying heating scenarios, and oscillate the meniscus over a range of frequencies. It’s anticipated that our device can be utilized by the RIT Thermal Analysis, Microfluidics, and Fuel Cell Laboratory in order to gather a more robust comprehension of bubble nucleation and enhance heat dissipation in a broad range of applications.

Current bill of materials
Presently, we have spent $1,040.67 of our $5,000 budget. We spent no additional money during this phase.
|2.5" round speaker from Jameco Electronics||$6.09|
|6.5" round speaker from MCM Audio||$33.68|
|6061 Aluminum round rods||$249.37|
|Teflon PTFE 0.01" gasket material||$17.76|
|Carbide turning inserts||$33.75|

Updated Gantt ChartThe following dates were altered on the Gantt Chart:
- Purchased all components.
- Completed design of final test fixture within an additional week of time.
- Extended date to complete all testing by one week.
A PDF of the updated Gantt Chart can be viewed by clicking here. Images of the Gantt Chart can be seen below.
IMPORTANT: We fixed the clock.
After one and a half semesters of looking at a non-functioning clock and mumbling about how somebody should fix it, we finally installed new batteries and are now happily enjoying a new and fully functional clock.
