KGCOE MSD SDR Technical Review Agenda P13621: Heat Transfer Conduction Lab for Chemical Principles Lab


Project Overview

Project Name: Chem E Lab Equipment

Project Number: P13621

Project Family: ME and ChE Lab Hardware

Start Term: 2012-1

End Term: 2012-3

Mission Statement: To provide students with the

ability to observe conductive heat transfer and the

ability to measure the thermal conductivity of a

material.

Project Background/ Problem Statement:

The transfer of heat through a material in any

state is the process of heat transfer. Conductive

heat transfer through a solid has been done for

years in industry to heat or cool materials. The

materials ability to transfer heat is a measurable

quantity called thermal conductivity. Scientists

have an in-depth understanding of this material

property and have published data for various

materials. The chemical engineering department

is creating a laboratory experiment for observing

conductive heat transfer and measuring thermal

conductivity of multiple materials. This will

yield experimental results comparable to the

current published data.

Objectives/ Scope:

1. Develop apparatus for students to observe

conductive heat transfer and measure thermal

conductivities of various samples

2. Ability for students to compare experimental

results to published thermal conductivities

3. Obtain data from manual measurement and

DAQs

4. Visually demonstrate conductive heat transfer

5. Steady state heat transfer conditions

preferable; transient heat transfer conditions

optional.

Deliverables:

1. Conductive Heat Transfer Apparatus

2. Documentation to reproduce apparatus

3. Final Wiring Schematic

4. 3D modeling prints

5. Manufacturing spec sheets

6. Assembly instructions

Project Team:

Tatiana Stein (ChemE) – Team Facilitator

Rushil Rane (ISE) – Lead Engineer

Shayne Barry (ME) – Procurement

Jordan Hill (EE)

Piotr Radziszowski (ME)

Meka Iheme (ChemE)

Shannon McCormick (ChemE) – Project

Manager

Guide, customer & other attendees:

Neal Eckhaus – Guide

Steve Possanza – Guide

Karuna Koppula – Customer

Chinmay Patil – Field Expert

Expected Project Benefits: Students fully understand fundamental conductive

heat transfer concepts through observation and

experimentation. They will compare experimental

data with published thermal conductivities. Use

apparatus for demonstrations to students in other

engineering departments.

Assumptions:

To keep analysis simple for laboratory students, the

team must assume 1D steady state heat conduction

and the team must neglect losses.

Issues & Risks:

Successful integration of mechanical and

electrical subsystems

Proper documentation to quickly get back on

track in the spring

Ensuring simplicity for teaching students

Figure 10: Pugh Matrix for Thermal Insulation. Result: Fiber glass because of its low thermal conductivity, price, and

robustness.

Figure 11: Pugh Matrix for Providing a Heat Source. Result: Vertical heat plate is the best because of its price, ability

to allow for manual data collection and accurate provision of electrical heat flux.


Figure 12: Pugh Matrix for Recording Sample Dimensions. Result: Calipers and stopwatches because they are

relatively cheap, perform the most accurate measurements and can be quickly reset.

Figure 13: Pugh Matrix for Sample Holding. Results: Meter Bar + Heat sink offer the best options of cost and

insulation to prevent heat losses to sample holding.

Figure 14: Pugh Matrix for Temperature Acquisition. Results: Thermocouples because they have the best option for

bare surface area required and will yield the most accurate results.


Figure 15: Pugh Matrix for Temperature Display. Results: LED Readout and thermal crayon resulted as the best

concept for temperature display because of their safety, temperature range and relatively low cost.
