  1. Educational Apparatus to Demonstrate 1-D Conductive Heat Transfer Charles Pueschel Ian Abramson Alysha Helenic David Olney Todd Jackson Edward Turfitt Project 13623

  2. Project Description Create an educational apparatus to demonstrate 1-dimensional conductive heat transfer and allow students the ability to measure and calculate the thermal conductivity of a material using the concept of Fourier’s Law.

  3. High-Level Customer Needs • Enhance student experience and demonstrate core heat transfer topics from Continuum Mechanics I • Equipment must be compact, mobile, durable, and reproducible • Equipment must be safe for users and observers and and the lab must be able to be replicable multiple times in a lab period • Equipment must demonstrate steady state heat conduction, allow for data to be collected manually, and provide the means to calculate the thermal conductivity or a variety of samples

  4. Selection of Engineering Specifications

  5. Team Roles • Team Lead – David Olney • Engineering Lead – Todd Jackson • Physical Build – Edward Turfitt, Ian Abramson, and Todd Jackson • Programming and Electrical – Charles Pueschel and David Olney • Documentation – Alysha Helenic

  6. System Design Pros • Visual • Compatible with different length and diameter samples • Pressure can be applied on both the heater and cooler • Compatible with multiple insulations

  7. AutoCAD Model

  8. Subsystem Components Cooling: Cold Plate Heater: Insulated Sheet Heater Data Collection Temperature Sensors

  9. Design Summary

  10. Initial System Testing

  11. Schedule Comparison Budget Comparison • Original Budget: $1,200 • Final Cost: $1,040.30 • Difference: $159.70 • Savings from: • Donations • Waived tax • Design Verification took longer than expected (until week 13) • Continuously obtained parts throughout semester as needed

  12. Opportunities and Suggestions for Future Work • Further testing to prove reproducibility of results • Add a dial to directly control temperature of heater • Integrate pressure sensors into the temperature sensors to control quality of contact between sensor and sample • A way to hold pastes or liquids in order to test the conductivity of materials that are not solid Temperature Dial “Boat” to Test Non-Solids

  13. Project Self-Evaluation • If we were to redo the semester, we would have done more building and programming earlier to allow more time for testing the whole system • Overall the group worked well together and everyone completed the work they were responsible for on time
