Integrated System Build & Test

Team Vision for Integrated System Build & Test PhaseDuring this phase, our team improved the physical system after analyzing the results from our 4th burn cycle. New parts were ordered to compensate for the changes. Additionally, our team began writing the training manual and requirements to ensure success and a more repeatable process.
By the end of this phase, we further refined our mathematical model and simulations to provide greater insight on the factors that most affect the system (i.e. pipe diameter, material). This allowed our team to confidently report to our customer and move towards eliminating other risks in our design.
Test Results Summary
Analysis: Temperature Data
For the Integrated System Build and Test, our team made improvements to the system by adding new elbow connectors to prevent leakage and melting of material and by acquiring dried twigs and branches for burn material. This was the 5th burn trial completed by the team. The details of the testing conditions are outlined in the timeline below:

placement of the thermocouples and the newly added elbow
The final results from the test are summarized below:
|Starting water temperature||5 °C||41 °F|
|Increase||+30.8 °C||+55.44 °F|
|Ending water temperature||35.8 °C||96.44 °F|
|Amount of water heated||12.75 gallons|
|Time elapsed||1.12 hours|
|Ambient temperature||-6.67 °C||20 °F|
After modifying the system and performing a burn with correct material, the target temperature was achieved, and within the target time allowed. This further proved the capability of the system and gave insight on the system's robustness. Despite cold ambient air and reservoir water temperatures, the system heated the water within almost an hour.
Test Plans Status
Five of the tests were resolved during the second round of testing:
- S1 Test Plan: Temperature of output bathing water
- S4 Test Plan: Average burn time
- S7 Test Plan: Time to heat the recovery system to ideal water temperature
- S8 Test Plan: Heat recovered from working fluid/hour
- S9 Test Plan: Volume of water heated by the system
