Physical and quantitative observations of some elementary behaviors found in fluid mechanics:
aerodynamics of airfoils and wings, blunt body flows and boundary layers.
Course Objectives: To become independent problem solvers through a fundamental learning of fluid mechanics. Prerequisites:
Credit with a grade of at least C or registration for Aerospace Engineering 320 and 333T (or another
approved engineering communication course), and Mathematics 427L with grade of at least C.
Knowledge, Skills, and Abilities Students Should Have Before Entering This Course:
Strong knowledge of differential and integral calculus, basic engineering physics, basic programming (e.g. Matlab, Excel,
Mathematica, etc.), plotting and graphics, and word processing.
Knowledge, Skills, and Abilities Students Gain from this Course (Learning Outcomes):
Students will gain intuition about fundamental behaviors of fluid flows, an understanding of basic experimental methods and the
aerodynamics of aircraft. Students are expected to gain a better understanding how to construct a quality technical report and work in
a team oriented setting.
Impact On Subsequent Courses In Curriculum:
Material is presented as co-requisite with that of ASE 320 and is most important for subsequent courses in viscous and compressible
flows, propulsion, flight mechanics, aircraft design. Relationship of Course to Program Outcomes:
This course contributes to the following ABET Criterion 3 outcomes and those specific to the EAC accredited program.
a. An ability to apply knowledge of mathematics,
science, and engineering
b. An ability to design and conduct experiments,
as well as to analyze and interpret data
c. An ability to design a system, component, or
process to meet desired needs within realistic
constraints such as economic, environmental,
social, political, ethical, health and safety,
manufacturability, and sustainability.
d. An ability to function on multi-disciplinary
e. An ability to identify, formulate, and solve
engineering problems √
g. An ability to communicate effectively √ h. The broad education necessary to understand the
impact of engineering solutions in a global,
economic, environmental, and societal context.

engage in life-long learning √
√ j. A knowledge of contemporary issues
√ k. An ability to use the techniques, skills, and
modern engineering tools necessary for engineering
practice √ f. An understanding of professional and ethical
ABET Program Criteria Achieved:
B. Aerospace Materials
E. Flight Mechanics
F. Stability and Control √
√ G. Orbital Mechanics
H. Space Environment
I. Attitude Determination and
√ K. Space Structures
L. Rocket Propulsion √ √
M. Preliminary/Conceptual Design
N. Other Design Content
P. Computer Usage √ Topics:
The course emphasizes a laboratory based learning of the fundamental behaviors of fluid flows through
an examination of the flows around airfoils. Flows about spheres are considered in detail as a prototypical flow about a blunt body in
which the state of the boundary layer is of great significance. Group projects will emphasize different aspects of fluid mechanics,
which will be chosen and designed by the members of a particular group. Students will also become familiar with several common
flow measurement techniques: (1) Laser Doppler Anemometry (LDA), (2) Pitot-Static tube, (3) Constant Temperature Anemometry
(CTA), (4) Flow-Visualization, and (4) wind and water tunnel operation. Safety is discussed although none of the equipment is
especially hazardous. Specific lecture topics are highlighted in the Expected Schedule.
There are several aspects of this course that relate to engineering professionalism. In particular, the
student’s ability to clearly communicate their findings from each laboratory is weighted heavily in the grading. Also, in the third lab
study, students will execute their experiments as part of a group effort. Thus, teamwork will be essential for this component of the
course and grades will be weighted based on participation of the individuals in their respective groups.
Depending on the projects chosen by each group, there may or may not be a design component. If a
group chooses to build and instrument its own model, then design work will be involved. Students interested in a specific project
should discuss their ideas with me early in the semester.
The laboratory assignment will comprise three technical reports, each of which will be due to the
Professor subsequent to performing the laboratory.
Students will use a computer to prepare all written reports. Students may use a computer to download
electronic video or still images for analysis in any software package of their choice (e.g., Photoshop). Students may also prepare
contour plots of field data using software of their choice (e.g., Tecplot, Matlab, Excel or Mathematica).

Fluid Mechanics Measurements, ed. R. Goldstein (reserve)

Other texts are on reserve in the Engineering Library
Laboratory tests will be conducted in groups of about five or six students. Each group is allowed two
hours for the first two laboratories. This is fully adequate provided you understand the assignment before you come to the lab.
Formal individual lab reports are due two weeks after the end of your lab period and must be printed on a word processor and
submitted in both hard copy to me and electronic format to the TA (e-mail, text only). Report format, grammar, and spelling will help
determine your report grade. The large group project lab time will be scheduled later in the semester.
Lab Test Schedule
(1) Airfoil Study Sept 14-18
(2) Drag on a sphere Oct 12-16
(3) Group Project Nov 9-20 (Schedule lab time with TA)
Grading: Laboratory #1
Laboratory #3 or Group Project 25%
4 0% Homework Policy:
There will be no homework assignments, although students are expected to read assigned material
before showing up to the laboratory.
Examinations: There will be no examinations. Grades are based on performance of laboratory reports. Attendance: Regular attendance in Lecture is expected. Regular attendance in laboratory is mandatory! NOTE: Missed labs MUST be made up during the scheduled week of the test because a new set-up will be installed at the end of the
week. You MUST attend the lab to get a grade for the lab. Failure to turn in reports will result in an F for the class. Copying or
paraphrasing the work of another without proper attribution is plagiarism subject to the University policy on cheating. You may utilize
ONLY the old lab reports that I provide directly to you.
Office Hours: To be announced. For now: TTH in WRW-301A, 3:00 – 4:00pm. Scheduled appointments or walkins are always welcome.
