Course Objectives:

Intermediate Mechanics of Fluids follows ENGR:2510 (57:020) Mechanics of Fluids and Transport Processes in the undergraduate curriculum at The University of Iowa and is suitable for senior-level undergraduates and beginning-level graduate students. Since students are expected to have had only one previous course in fluids, the only prerequisite for this course is 57:020 or an equivalent course from another university. For students who have taken more than one course in fluid mechanics, it is recommended that they take more advanced courses Inviscid Flow and Viscous Flow; however, in some cases, the present course may be useful as review for the Ph.D. Qualifying Exam. The course provides background for more advanced courses in fluid mechanics, heat transfer, and other engineering disciplines such as hydraulic, bio, or chemical engineering or for greater understanding of fluid mechanics for students who wish to enter engineering practice after the completion of the B.S. degree.

The course provides a more in-depth treatment of analytical fluid mechanics (AFD) and computational fluid dynamics (CFD) than is possible at the level of the first course. The first part of AFD is devoted to basic concepts, integral and differential equations of fluid motion, boundary conditions, exact solutions, inviscid approximations, and dimensional analysis and similarity.  The second part of AFD is concerned with the theory of incompressible laminar and turbulent viscous and inviscid flows with selected applications. Internal and external flows: laminar and turbulent viscous flow in circular and non-circular ducts; duct systems and losses; laminar and turbulent boundary layers; lift and drag; and potential flow theory.

Teaching:

The class website provides all the course materials, including lecture notes, CFD lab handouts and assignments, and schedule including reading and homework assignments and due dates cross referenced to lectures and concepts.  Lectures will present website lecture notes etc. with additional discussion, using the overhead projector.  Students should not take detailed in-class notes copying this material since it is available and can be printed out or used with digital note taking software but should rather augment website material with notes based on additional discussion, which supplement and expand on website material.

Class attendance:

Class attendance is required except for legitimate reason submitted prior to the missed class.

Homework Assignments:

Homework problems are assigned to reinforce classroom lectures (to be done independently or in a group with caveat that students must be prepared to take quizzes and tests independently), must be handed in on time, and are graded. Additional comprehensive homework problems will be required for graduate students and accounted as extra credits for undergraduate students. Solutions to the homework problems are posted to the class website after the due date. Late submission will not be accepted except for legitimate reason submitted prior to due date. One third of the assigned homework problems will be selected randomly and graded by the HW TA, who will hold regular office hours and should be consulted in case of difficulty in the solution of problems or questions concerning grading. Each problem will be graded based on 10 points.  Homework accounts for 10% of the final grade.

Homework solutions should be prepared in the following format:

NAME and University ID

KNOWN:                   Problem statement, relevant figure drawn to scale, list of variables known

FIND:                          To be determined?

ASSUMPTIONS:       List of assumptions/limitations of solution, formulas, constants, units

ANALYSIS:               Details of the work using appropriate units and significant digits

The HWs will be graded following the HW grading guidelines.

Important Note: It is not acceptable to copy from the Solution Manual and suspected HWs will be rejected.

CFD Labs:

There will be 4 CFD take home projects which are to be done independently and handed in on time, and a CFD pre- and post-test. CFD lectures and laboratory exercises utilize a hands-on CFD educational module conducted for both internal and external flows.  The CFD educational exercises utilize the industrial CFD code ANSYS Fluent and are designed to teach students CFD methodology (modeling and numerical methods) and procedures through a step-by-step interactive implementation that mirrors actual engineering practice. ANSYS Fluid software can be accessed at any computer lab in the Seamans Center.

 

 

Examinations:

1. There will be two in-semester 50-minute and one final 120-minute examinations, on the dates shown on the Class Schedule.

2. Exams may include standard problems as well as multiple-choice, short answer, and true-false questions. Examinations may include problems previously assigned for homework.

3. Students may prepare and bring a one-page (one side) formula sheet to exam 1, one-page (two sides) to exam 2 and two-pages (three sides) to exam 3. Formula sheets must be in the student’s own handwriting (no Xerox) and can only include definitions and formulas. No homework/example problems and no tables/diagrams are allowed. Students must put their name on both the formula sheet and exam, and hand it in along with their exam.

4. All exams are closed-book and closed-notes. Only the exam, exam booklet, calculator, and formula sheet(s) are allowed. No electronic device that stores information or has the capability to connect to the Internet will be permitted during the exam, including cell phones.

5. Failing to follow the above policies (items 3 and 4) will be considered as an academic misconduct and subject to penalty.

Pop-quizzes:

1. Pop-quizzes will be given randomly, approximately once every week or more frequently if attendance is low and/or quiz grades are low. To reinforce this policy, an extra credit of 10%, 5%, and 2.5% of the overall quiz score will be given for missing no quiz, one quiz, and two quizzes, respectively, throughout the course.

2. All quizzes are closed-book and closed-notes. Only calculators are allowed. Electronic devices that store information or have the capability to connect to the Internet will not be permitted during the quizzes, including cell phones.

3. Make up quizzes will not be given except for legitimate reason submitted prior to class.

4. General guidelines for pop-quiz grading can be found here.

Grading:

The final grade will be based on Pop-quizzes + Two in-semester exam+ Final exam+ Homework + CFD take home project and post-test as follow:

            Two in-semester exams, 12.5% each                                                                 = 25

            Final examination, 25%                                                                                      = 25

            Homework problems, 10%                                                                                = 10

            Pop-quizzes, 15%                                                                                              = 15

            4 lab reports (5% each), post-test, 5%                                                                = 25

                                                                                                                                   -------

                                                                                                   TOTAL                        100 points

Academic Misconduct
