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
