EML **** Thermo-Fluids I

Thermal-Fluids I

Course Syllabus:

This course is the first part of a newly designed two-course sequence on thermal and fluid sciences. These new courses combine the traditional thermal disciplines in Thermodynamics, heat transfer and fluid mechanics into one integrated subject: Design and analysis of thermal systems. Case studies based on real-world thermal systems will be used throughout the class to illustrate the relationship between these interdisciplinary subjects. The lecture materials cover: Fundamentals of Thermodynamics, First and Second Laws of Thermodynamics, various power and refrigeration cycles, heat transfer modes including steady and unsteady conduction, convection and radiation, flow statics and buoyancy, mass, momentum and energy conservation, Bernoulli equations, internal and external flows. The following objectives will be accomplished after the completion of this class:

To learn the fundamentals of engineering Thermodynamics, heat transfer and fluid mechanics.

To learn techniques for formulating and solving thermal and fluid problems with emphasis on using an integrated and just-in-time teaching strategy.

To prepare students for Thermal-Fluids II and other advanced courses in thermal science.

To prepare students for competence in the workplace through cooperative group works and more computer-based teaching and learning.

Textbooks:

Introduction to Thermodynamics and Heat Transfer

by Yunus Cengel

Introduction to Fluid Mechanics (will be needed for Thermal fluids II)

by Fox & McDonald

PREREQUISITES:

This course requires that you have taken and passed (with a C or better) the following courses:

PHY 3048, Physics I; MAC 3312, Calculus II; MAC 3311, Calculus I, Engineering Math I & II, Dynamical System I.

If you have not passed these courses, you are not prepared for this course and the instructor has the right to drop you from the course. Request for exemption should be made during the first week of class.

Homeworks:

Each student will be assigned to a group of 3 or 4. Each group will only need to submit one set of homework solutions. NO CREDIT will be given for late homework. Homework solutions will be provided soon after the problem set is due. I will assign the group and post the group assignment on the web page the first week.

DETAILS: Homework is to be written on 8.5" by 11" paper - ONE SIDE only. One problem per page. Pages must be stapled together. No credit will be given for homework that does not comply with these details. Homeworks always due one week after the assignment. All members who sign on the homework sheet will receive the same credit. Dispute should be worked out among members before submission. It is your responsibility to arrange regular meeting between members to equally distribute the work load.

Workshop Assignments

Additional problems will be assigned each week during the workshop period. The assignments should be worked in groups in computer labs. This group assignment will be the same as the homework group to reinforce cooperative learning experience. Each goup is going to submit one report before the end of the workshop period. All members will receive the same grade.

Grading Assignment:

Homework 10 %
Quizzes 10 %
Lab 10 %
Project 10 %
3 tests 40 %, scheduled, Highest two count 15 % each
Final 20 %

Grading Scale:

90 - 100 A

80 - 89 B

70 - 79 C

60 - 69 D

0 - 59 F

Departmental policy is that a grade of C or better is required to pass this course.

ATTENDANCE:

Attendance is mandatory and always be ON TIME. Unexcused absence(s) will adversely affect your final grade. In accordance with the policies of the universities, students with more than 3 UNEXCUSED ABSENCES will receive an automatic F. Excuses must be turned in to the instructor within two weeks of the absence.

CHEATING

Students caught cheating on an exam or quiz will receive an F for the class.

GROUP PROJECTS

Each group will be responsible for formulating, designing and building a thermal system that illustrates concepts learned from the course. The project will be formulated using the design principles learned in Introduction to Mechanical Engineering. Design details and project suggestions will be provided later.

QUIZZES

Each student is responsible for reading the course materials ahead of scheduled class time to eliminate unnecessary class lectures on formula derivations. This allows class time to be more focused on problem solving and concept discussion. Quizzes, both scheduled and unscheduled, will be given each week to evaluate the students’ readiness. There will be NO MAKEUPS for missed quizzes. All quizzes are closed book; necessary formulas will be provided. Warning: quizzes will be given before, during and at the end of the class period. So there is no excuse that you leave earlier during lecture.

EXAMS

In addition to quizzes, there will be 3 scheduled in-class exams: No makeup exams will be given unless legitimate excuse is provided with the approval of instructor. All exams are closed book; necessary formulas will be provided. The highest 2 grades will count 15% each while the lowest counts 10% toward your final grade;

FINAL EXAM

A comprehensive final exam (20% of the grade) is scheduled during finals week. The final exam is closed book; necessary formulas will be provided.
