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.

Homework
1. Homework problems are assigned MWF, are
due WFM, 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 a legitimate reason,
explained in writing at the time of submission.
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 15% 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 books.
Students may prepare and bring a one-page formula sheet to exams.
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.
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, 15% each =
30
Final examination, 30% =
30
Homework problems, 15% =
15
5 lab reports (4% each), post test, 5% = 25

TOTAL 100 points
Class website http://www.icaen.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.
