VERY IMPORTANT: Prerequisite for this MEE 640 ADVANCED FLUID MECHANICS is the undergraduate MEE 340 Fluid Mechanics or equivalent. Therefore, it is VERY important to review the related materials from our Supplementary (undergraduate) Text or equivalent before reading and studying our graduate Textbook materials. Usually, an undergraduate text starts from and explain physical concepts first and then derive related analytical correlations (usually easier for beginners), while a graduate textbook may use general and advanced mathematical tools to describe and "explain" physical concepts in general, thus missing some subtle  and basic details critical for a novice learner.

Answer Forms: Quiz/Midterm/Final Exam; Multiple Choice; HomeWork (HW) form must be used as first page for all HWs as explained in class. We have established a rule to give full credit for fully and accurately solved problem by the due date, and half the credit for redone problem by the next class meeting after the solution is posted (only if you fully comprehend the posted solutions; thus no credit for partially solved problem).

NOTE: Special Projects assigned verbally in class on October 6th are:
5 Vorticity Dynamics (Vishnu Vardhan Reddy Pati - vrpati0618@gmail.com, due 10-20-09); Ch. 6 Irrotational Flow (Phani Ganesh - phani_67@yahoo.com, due 10-20-09); Ch. 9 Laminar Flow (Bhaskar Rao Tulimilli - tulimillibhaskar@gmail.com, due 10-27-09); Ch. 10 Boundary Layers and Related Topics (Sudhir Kumar - sudhirlv@gmail.com, due 11-03-09); Ch. 13 Turbulence (Jim Hill, due 11-17-09).

Special Projects are assigned at least two weeks before the class presentation (due date), the PPT file should be emailed to me at least 36 hours before the presentation due day, may be "improved" after that, and should be finalized within one week after the presentation. Accomplishments and quality of work of all phases, including presentation, will be graded.
As detailed and explained in class, you are expected to study related undergraduate and graduate textbook chapters thoroughly with full comprehension (including additional researched materials in related references and Web resources) and prepare a PPT presentation (and be able to answer all questions and explain related concepts) for your presentation on the related chapter reading assignment due date, and for the following class meeting to submit written report reflecting comments and suggestions during class presentation, as explained in class. Note that class PPT presentations has to have at least one typical quantitative problem (of your choice) solved with physical explanation as discussed in class. For example, for the Irrotational Flow reading assignment of October 6th (and previous covered chapters), students should prepare a PPT presentation and be ready for presentation on the October 20th, the reading assignment due day and submit written report and finalized PPT file on October 27th (the following class meeting) and so on. A HW will be assigned (for all students but the presenter) to submit in writing individual comments, evaluation and suggestions for special project assignment presentations (email and print and submit as regular HW, email due 60 hrs after the presentation, and printout for the next class after each Project presentation) with an objective to demonstrate your comprehension and increase learning value to the class audience (thus you).

Staple together in this order from top to bottom: Quiz/Midterm/Final Exam answer form, 8-sheet-blank-paper-set (exactly and must be submitted even if blank) and Multiple Choice answer form, and bring it with your personal Textbook, printed/copied Approved Handouts (bounded with your name: stapled or in a single 3-ring folder), pen, pencil and a calculator, etc. Write on the front face of the Worksheets only and end each page to be graded with "See Next" and "The End" for last page used.
IMPORTANT NOTE: If you have more than two Final Exams on the same date you have a right to reschedule an exam. Please email to me the exact schedule of your exams (courses and dates/times) and then come in person to my Office to reschedule an Exam before our last class meeting.

 

All students and TA should check that all relevant links needed for Final exam are working before our last class/lecture. Check if your name is properly spelled or missing in our Class Photo and email to me if any correction is to be done.
