Course Description: This course is an advanced fluid mechanics course covering graduate level fundamental understanding of turbulent flow in general and turbulent boundary layers and boundary layer type flows such as jets wakes and shear layers. A short discussion on laminar boundary layer will be presented before the turbulent flows. Different scales of turbulent flows, similarity and solutions to equations will be discussed. Turbulence modeling used to simulate these flows will be covered, particularly Reynolds averaged Navier-Stokes equations solutions will be discussed in detail. Examples form Prof. Yavuzkurt’s research in the area of turbulence model development will be briefly covered if the time allows. Extensive course notes will be available online. Course Outline: 1. Incompressible Laminar Boundary Layers 2. Turbulent Flow 3. Turbulent Shear Flows 4. Turbulent Flows near Solid Surfaces 5. Models of Turbulence and Application to Boundary layers 6. Some of Prof. Yavuzkurt‘s Studies on Turbulence Modeling

Undergraduate Fluid Mechanics , Calculus, Differential Equations

Course will be taught via lectures given by Prof. Yavuzkurt. He will write on a tablet computer and project them on screen. Later he will put the lecture notes up on course web site. He will ask questions and discussion will be encouraged. Students will present their term papers at the end of the semester, this will give a chance for the students to learn from each other and to apply the knowledge the have learned in class.

Grading Homework 10% Homework will be handed out in class and collected in class on the due date specified. No late homework will be accepted. Homework will be grades as: Good (Substantial amount of work 10 points), Satisfactory (Acceptable amount of work 7 points), Poor (Very little work 5 points) Not handed in on time (0 points). Solutions will be available after homework is collected. It is up to the students to compare their solutions with the ones supplied by the instructor. Exam #1-In class 30% Exam #2-In class 30% Term Paper (Due week before the end of semester - in class) 30% Topics for term papers will be chosen by discussions with me after a literature survey. It will involve a solution of a turbulent flow convective heat transfer problem by use of computer codes FLUENT or OpenFOAM. Any other CFD code can be used or you can write your own code. There will be no teaching of the codes in class. Students are expected to learn these from tutorials. You might benefit from tutorials on Prof. Cimbala’s web page http://www.mne.psu.edu/cimbala/Learning/learning.htm. If you have a research topic you are already working on you can use a topic related to your research. Topics should be chosen by the second week of the semester. Papers will be presented in class by each student. About 10 minutes will be allowed for each presentation depending on the number of students. Presentations will take place about the last or last 10 days of the course. Term Paper grade will consist of: Report 60% (90% technical part, 10% clear writing, language usage etc.) Oral Presentation 40% (80% technical part, 20% presentation) Reports should be written with a word processor (no handwriting, including equations and figures). Presentations could use transparencies or power point or similar. ATTENDANCE: Students are strongly encouraged to attend class and interact with the professor. This is part of the learning. Although I am planning to put up the lectures online your attendance and discussion in class makes the course much better. If I see that the attendance is dropping because the class notes being available on line, I might stop putting them up and/or start taking attendance and consider attendance when I give final grades. Therefore, please come to the class unless you have an acceptable excuse.
