ANNOUNCEMENTS:
INSTRUCTOR: Javier Urzay. Office: 206 CTR Building.
E-mail: jurzay@stanford.edu
LECTURES: Tuesdays and Thursdays, 11:00 AM-12:15 PM at 240-101 (Main Quad, east side). OFFICE HOURS: Mondays 9:00-11:00 AM at 206 CTR Building. COURSE SYLLABUS: (PDF) PREREQUISITES: ME 361 Turbulence, ME 371 Combustion Fundamentals, or consent of instructor. COURSE DESCRIPTION: This is an introductory course focused on theoretical aspects of Turbulent Combustion. A review of fundamental concepts of combustion and turbulent flows is performed. Characteristic scales and combustion diagrams are presented, and basic turbulent-combustion models for premixed and non-premixed combustion are discussed. Time permitting, fundamental concepts in spray combustion will be presented. Some emphasis is made to identify key physical processes in practical applications for propulsion and power generation. REFERENCE TEXTBOOKS EXAMS: Midterm Exam: Tuesday, May 15, in class.
Final Exam: Tuesday, June 12, location TBA.
Both exams will consist of two parts: i) Short Questions (closed books, closed notes, no calculator), and ii) Problems (open book and open notes, calculator allowed).
GRADING SCHEME:20% Homeworks + 35% Midterm Exam + 45% Final Exam. REGRADING POLICY: Please contact the instructor for exam regrades. ACADEMIC INTEGRITY: The Stanford Honor Code will be followed. ACCOMODATIONS FOR STUDENTS WITH DISABILITIES: Requests for
appropriate accommodations must be presented to the instructor.
HOMEWORKS: There will be 3 homework assignments. No late homeworks will be accepted. SUPPLEMENTARY MATERIAL MIDTERM EXAMS, HOMEWORK ASSIGNMENT AND SOLUTIONS. Description Due date:
