Textbook:
Fluid
Mechanics, 9th Edition McGraw Hill, White.
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
