Height Adjustment - Preliminary Testing RIT Thermal Analysis Microfluidics ● Stage found in the lab and Fuel Cell Lab ● Has relatively fine adjustment ● Need to fabricate base plate to mount it securely to the isolation table 12/10/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 14

Height Adjustment - Preliminary Testing RIT Thermal Analysis Microfluidics ● For flexibility of injection system to allow for needle to move chose brake and Fuel Cell Lab lines ● Can withstand high pressures (3,000psi+) ● Robust and cost effective 12/10/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 15

The Oscillator - Preliminary Testing RIT Thermal Analysis Microfluidics ● Approached Dr. Lam to discuss speaker dampening and Fuel Cell Lab ● 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 12/10/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 18

The Oscillator - Continuation RIT Thermal Analysis Microfluidics ● Ordered Materials and Fuel Cell Lab ● 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 12/10/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 19
