11:30 - 12:20 MWF 100PH

Instructor: Professor Frederick Stern

Office Hours: 223C HL, 12:30 - 1:30 MWF (or by appointment)

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, i.e., personal/family emergency or required university event .

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 except for legitimate reason submitted prior to due date.

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

NAME:

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.

4. One of the two daily assignments will be randomly selected and graded with full credit for other if handed in. The full credit is 10 points for each assignment. Homework accounts for 10% of the final grade.

6. General guidelines for homework grading can be found here.

7. You will not receive any credit for your homework if you copy the solutions manual for the class textbook.

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 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 Hydraulics East Annex and 3231 SC, respectively. 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. The deadline for EFD data reduction and EFD/CFD lab reports for each group is due six days after and two weeks after the lab is completed, respectively (also see Class Schedule). Lab reports should be submitted by 5:00 PM on the due date at the fluids lab report box outside 2416 SC. Late submission will not be accepted except for legitimate reason submitted prior to due date.

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. 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 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 fluid id 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 (i.e., no 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 one or two weeks 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 calculator are allowed. Electronic devices that store information or have the capability to connect to the Internet will not be permitted during the quizzes (i.e., no 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 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 printed out or used in a digital note taking software, but should rather augment website material with notes based on additional discussion, which supplement and expand on website material.

Academic Misconduct

College of engineering academic misconduct policy can be found here, and will be followed strictly.
