Project OverviewMission Statement: To provide students with the ability to observe conductive heat transfer and the ability to measure the thermal conductivity of a material.

Background:

A material’s ability to transfer heat is a measurable quantity

RIT ChemE department would like to procure lab equipment that would demonstrate heat transfer such that students may be able to calculate thermal conductivity

Experimental results would be comparable to published data

Objective Project Evaluation

Overall Success.

Thermal conductivity accuracy >85% for 3 of 4 samples tested. (including 99% accuracy for Aluminum)

All risks in Risk Assessment were mitigated over the course of MSD I & II.

Suggestions For Future Work Shorter Cartridge heater- modified to accept a shorter cartridge

heater (less than the standard drill length ~ 4”) then creating the copper block may have been slightly easier.

Since the last ¼” to ½” of the cartridge heater has no heating elements and is more insulation for the connecting wires than anything else, it is a good idea to keep them outside of the copper heating block.

Controlling the temperature at the boundary between the heating block and the specimen could reduce time to steady state and possibly create more accurate results.

Decreasing sample size

Using thermal grease

Using High K material samples for samples
