Course Objectives:

This is a first course in fluid mechanics.  It provides an introduction to basic concepts in fluid statics, kinematics, and dynamics.  Control-volume and differential equation and dimensional analysis methods are derived and used to demonstrate applications to simple external- and internal-flow fluids engineering systems to determine variables of interest (pressure; shear stress; velocity distributions; flow rates; forces; energy losses; power requirements; etc). Homework assignments, tests, and complementary experimental and computational fluid dynamics (EFD and CFD) laboratories are integrated into the course, which reinforce the theory and its practical application.  The EFD laboratories introduce fluids engineering facilities, measurement systems (equipment and data acquisition and reduction methods) and uncertainty assessment methodology and procedures.  The CFD laboratories introduce fluids engineering simulation based design methods, utilizing commercial industrial software Fluent along with a recently developed CFD educational interface.  The course provides the requisite material for other fluids, hydraulics, and heat transfer courses in the Biomedical, Civil, Chemical, and Mechanical Engineering programs.

Class attendance

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

Homework

1.        Homework problems are assigned MWF, are due WFM, respectively, and will be returned the following F.  Homework assignments should be submitted by 5:00 PM on the due date at the fluids homework box outside 2416 SC.  Late submission will not be accepted without penalty except for legitimate reason submitted prior to due date. Penalty for late homework may be substantial for more than one late submission. Late homework will not be accepted once solutions are posted.

2.         Homework solutions should be prepared in the following format:

NAME and SECTION

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

3.         Solutions will be posted on class website soon after the problems have been graded.  Consult these to correct your solutions for future reference.

4.        Homework problems will be graded by one of the Teaching Assistants, who will hold regular office hours and should be consulted in case of difficulty in solution of problems or questions concerning grading.

5.        Each problem will be graded on the basis of 10 points.  Homework accounts for 10% of the final grade.

Experimental and Computational Laboratories

1.        Complementary EFD measurements and CFD simulations are an important part of this course.  Each student must participate fully in the conduct of both EFD and CFD labs and in the compilation and analysis of the results.  Both labs are conducted by groups with group effort encouraged in the conduct of the EFD/CFD and analysis of results.  However, each student must prepare independent lab reports. Each student will be assigned a group on the basis of alphabetical order in the first class list for each section.  If students wish to form a different group, the instructor must be notified no later than the beginning of the second week of classes.

2.         The EFD measurements and CFD simulations are conducted in the instructional laboratories located in Iowa Institute of Hydraulic Research (IIHR).  Three EFD and two CFD labs will be conducted with separate reports required for three EFD labs (4% each) and two CFD labs (4% each). Pre (0%) and post EFD/CFD lab tests will also be given (5%).  Laboratories account for 25% of the final grade.

3.         Consult the EFD/CFD Lab Schedule for the dates on which each group meets, and for deadlines for the submission of the lab reports. (also see Class Schedule).

4.         More detailed instructions on EFD/CFD lab procedures and reports will be provided during special classes on EFD and CFD (see Class Schedule).

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.         All exams are closed notes and no books or cell phones or on-line computers. Students may prepare and bring a one-page formula sheet to exam 1, two-page to exam 2 and three-page to exam 3. Formula sheets must be in students own hand writing and can only include definitions and formulas. No homework or example problems and no diagrams.

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

4.         Pop-quizzes will be given randomly approximately every one or two weeks or more frequently if attendance low and/or quiz grades 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, respectivley, throughout the course.

Grading

The final course grade will be based on the total points earned during the semester.  The distribution of points is as follows:

 Two in-semester exams, 12.5% each                                                                 = 25

Final examination, 25%                                                                                      = 25

            Homework problems, 10%                                                                                = 10

            Pop-quizzes, 15%                                                                                              = 15

            5 lab reports (4% each), posttest, 5%                                                                = 25

                                                                                                   TOTAL                        100  points

Teaching

Class website http://www.engineering.uiowa.edu/~fluids/ provides all course materials, including lecture notes, EFD and CFD lab handouts and assignments, and grades for homework, laboratory reports, and tests.  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 downloaded and printed via the website, but should rather augment website material with notes based on additional discussion, which supplement and expand on website material.
