1/13 MER Design of Thermal Fluid Systems Professor Anderson Union College Spring 2012

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

3 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

4 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

5 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

6 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.

7 What is the point of this class?? Let’s check out the Course Web Page! Course Objectives and Outcomes: Upon satisfactory completion of this course students will demonstrate an ability to: 1.Work effectively and efficiently in teams 2.Lead / Manage projects 3.Communicate effectively in written, oral, and technical modes 4.Apply design principles to the design of thermal/fluids systems

8 What is the point of this class?? Let’s check out the Course WebPage! 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.

9 How are we going to do all that? Lets check out the Course Web Page again! 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

10 Topical Coverage Engineering Design: defining a need, specifying success criteria, identifying alternatives, analysis and optimization, design of experiments, the design report, team work. Thermal Science Review: thermodynamic fundamentals, fluid properties and basic equations, heat transfer fundamentals. Piping Systems: Piping and tubing standards, friction factors, pipe roughness, minor losses, major losses, valves, system behavior, measurement of flow rate and pressure drop. Pumps and Fans: types of pumps, pump characteristics, testing methods, pumps in series, pumps in parallel, fans, blowers, system design practices.

11 Topical Coverage Heat Exchangers: method of analysis, LMTD, heat transfer in a tube, double piped heat exchangers, shell and tube, cross flow, heat recovery, system design. Economic analysis: time value of money, comparing alternatives, depreciation and taxes. Optimization: Introduction and survey of mathematical methods of design optimization. Team Skills: Effective leadership methods, Efficient meeting skills, Conflict resolution, decision making methods, aspects of organizational behavior.

12 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.

13 Project 1 I will introduce the project and assign teams on Wednesday! (see project calendar for schedule) Today: Distribute Warm Up Take Home Quiz Engineering Economics Lecture 1
