Height Adjustment Responsibility: Rob RIT Thermal Analysis Microfluidics and Fuel Cell Lab 10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 11

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 10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 12

Height Adjustment - Preliminary Testing RIT Thermal Analysis Microfluidics ● For flexibility of and Fuel Cell Lab injection system to allow for needle to move chose brake lines ● Can withstand high pressures (3,000psi+) ● “Stainless Steel” lines have teflon tube to carry brake fluid, covered by stainless steel mesh for protection ● Robust and cost effective 10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 13

The Oscillator Responsibility: Alyssa RIT Thermal Analysis Microfluidics and Fuel Cell Lab 10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 14

The Oscillator - Preliminary Testing RIT Thermal Analysis Microfluidics and Fuel Cell Lab Left: Big speaker, water droplets on top of plastic membrane Center: Amplifier used to control speakers and volume Right: Mylar speaker with water droplets on top of plastic membrane 10/22/2015 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 10/22/2015 RIT Thermal Analysis Microfluidics and Fuel Cell Lab Slide 16
