1. What is this course? What is Design?
What are Thermal/Fluid Systems?
2. Course Overview (Rules, Projects)
3. Design Project #1 Warm Up

Where Does this Course Fit?
This is a capstone course. (Congratulations –
that means you made it to the near end!)
Mer439 builds on what you learned in Intro to
Engineering, Thermo II, Fluid Mechanics and
Heat Transfer (and all their pre-requisite
courses)
Mer419 (Machine Design) is a capstone
course that builds on Intro to Engineering,
Advanced Dynamics & Kinematics and
Strength of Materials

What is Design?
The design process involves the application of
concepts from engineering science in a generally
specified manner coupled with a creative touch.
(Boehm, 1987)
1. Conception - creativity
2. Synthesis - involves learned information and
creative insight
3. Analysis - learned concepts
4
Overview of Design Process
(1) Define the Problem
(2) List Design Requirements
(3) Generate alternative concepts
(4) Evaluate Alternatives and Select a Concept
(5) Detailed Design
(6) Oral Design Defense
(7) Manufacture
(8) Performance Evaluation
(9) Design Report

What is THERMAL/FLUID Design?
• Implies calculations and activities based on
principles of thermodynamics, heat transfer
and fluid mechanics.
• Components - fans, pumps, compressors,
engines, heat and mass exchangers, etc.
• Thermal systems generally use a large
number of components.
• Processes usually involve fluid motion.

Course Objectives and Outcomes: Upon satisfactory completion of
this course students will demonstrate the ability to:
5. Apply principals of engineering economic analysis
6. Identify ethical issues in engineering and be able to find
sources for guidance on how to ethically resolve these issues
7. Specify and design Pumping, Piping, and Heat Exchanger
systems.

How are we going to do all that?
Lets check out the Course Web Page again!
http://engineering.union.edu/~andersoa/mer439
You will complete four 2-week long design projects!
(last project presentation is scheduled during finals
week – SCHEDULED FOR Wednesday JUNE 6, 2012)
Your final course grade will be a combination of Group
and Individual grades
……let’s review the syllabus

My Roles…..
The Business Manager…..
• I am your boss or your boss’s boss (if you are working under
a team leader)
• I will meet regularly with team leaders to discuss team/project
management issues
The Technical Consultant….
• I have a PhD in the thermal fluid sciences.
• You may come to me for technical help … but I am
expensive! (1 hr/team/project for free thereafter it will cost 2
points per hour off final project grade charged in 15 minute
increments).
• Conceptual help on new material (economics, optimization
etc.) is free from your friendly neighborhood professor.
