Objectives
This course is an introduction to combustion processes. Combustion provides approximately 85% of the world’s energy, and is important in diverse range of applications including auto and airplane engines, power-plant boilers, waste incinerators, process heaters, cement kilns, wild fires, detonations, and fire hazards. Important concepts include fuel efficiency, control of pollutant emissions, and performance prediction for analysis and design. The following course objectives are defined: (1) Understand basic combustion processes including thermochemistry, combustion kinetics, premixed and nonpremixed flames; (2) Understand and appreciate the global impact of combustion and the breadth of applications; (3) Be able to perform basic combustion calculations involved in system analysis and combustor design.
Textbook
An Introduction to Combustion, 4th edition, by Stephen R. Turns
This book provides an excellent introduction to combustion processes, providing both fundamentals and applications. Topics will be treated selectively, with emphasis on gaseous combustion. You can also use the 2nd edition, as it is very similar and may be less expensive. See me for a correspondence between the two editions for reading sections and homework numbering differences.
Reading
Class discussions are designed to help students learn the course content, but many details and examples are given in the text. Your learning will require repeated exposure to the material and dedicated study.
Homework
Homework assignments will be due approximately weekly. Homework is designed to help you learn the course material through direct application. You are encouraged to work in groups, but you must turn in your own assignment, representing your own work. Late homework may result in decreased scores. You are on your honor not to use any solutions from any source in the working of late homework.
Exams
Two midterm exams and one final exam will be given. The final exam is currently scheduled for Monday, April 20, 2020 from 11:00 AM to 2:00 PM. This is the university scheduled time.
Grading
Grades for the course will be based on the following distribution:
- Assignments: 40%
- Midterms (2): 40%
- Final exam: 20%
Course Outcomes
As an introductory course in combustion, students will understand and appreciate the global impact of combustion processes and the wide breadth of applications.
Students will be able to perform basic combustion calculations involved in system analysis and combustor design.
Students will understand basic combustion properties and processes including the following:
- Adiabatic flame temperature, the mixture fraction, and chemical equilibrium
- Thermochemistry, and combustion kinetic mechanisms
- Pollutant formation mechanisms for NOx, SOx, soot, and CO
- Combustion in canonical reactors such as plug flow and perfectly stirred reactors
- Transport equations governing mass, momentum, and energy
- Laminar and turbulent premixed and nonpremixed flame theories, including flame speed, flame lengths, and basic scaling laws
- Concepts of flammability and ignition
- Solid and spray combustion models
BYU Policy Statments
Academic Honesty
The first injunction of the BYU Honor Code is the call to be honest. Students come to the university not only to improve their minds, gain knowledge, and develop skills that will assist them in their life’s work, but also to build character. President David O. McKay taught that “character is the highest aim of education” (The Aims of a BYU Education, p. 6). It is the purpose of the BYU Academic Honesty Policy to assist in fulfilling that aim. BYU students should seek to be totally honest in their dealings with others. They should complete their own work and be evaluated based upon that work. They should avoid academic dishonesty and misconduct in all its forms, including but not limited to plagiarism, fabrication or falsification, cheating, and other academic misconduct.
Honor Code
In keeping with the principles of the BYU Honor Code, students are expected to be honest in all of their academic work. Academic honesty means, most fundamentally, that any work you present as your own must in fact be your own work and not that of another. Violations of this principle may result in a failing grade in the course and additional disciplinary action by the university. Students are also expected to adhere to the Dress and Grooming Standards. Adherence demonstrates respect for yourself and others and ensures an effective learning and working environment. It is the university’s expectation, and every instructor’s expectation in class, that each student will abide by all Honor Code standards. Please call the Honor Code Office at 422-2847 if you have questions about those standards.
Preventing and Responding to Sexual Misconduct
The health and well-being of students is of paramount importance at Brigham Young University. If you or someone you know has experienced sexual harassment (including sexual violence), there are many resources available for assistance.
In accordance with Title IX of the Education Amendments of 1972, BYU prohibits unlawful sex discrimination, including sexual harassment, against any participant in its education programs or activities. The university also prohibits sexual harassment by its personnel and students. Sexual harassment occurs when
- a person is subjected to unwelcome sexual speech or conduct so severe, pervasive, and offensive that it effectively denies their ability to access any BYU education program or activity;
- any aid, benefit, or service of BYU is conditioned on a person’s participation in unwelcome sexual conduct; or
- a person suffers sexual assault, dating violence, domestic violence, or stalking on the basis of sex.
University policy requires all faculty members to promptly report incidents of sexual harassment that come to their attention in any way, including through face-to-face conversations, a written class assignment or paper, class discussion, email, text, or social media post. Incidents of sexual harassment should be reported to the Title IX Coordinator at t9coordinator@byu.edu or (801) 422-8692 or 1085 WSC. Reports may also be submitted online at https://titleix.byu.edu/report or 1-888-238-1062 (24-hours a day).
BYU offers confidential resources for those affected by sexual harassment, including the university’s Sexual Assault Survivor Advocate, as well as a number of non-confidential resources and services that may be helpful. Additional information about Title IX, the university’s Sexual Harassment Policy, reporting requirements, and resources can be found at http://titleix.byu.edu or by contacting the university’s Title IX Coordinator.
Student Disability
Brigham Young University is committed to providing a working and learning atmosphere that reasonably accommodates qualified persons with disabilities. A disability is a physical or mental impairment that substantially limits one or more major life activities. Whether an impairment is substantially limiting depends on its nature and severity, its duration or expected duration, and its permanent or expected permanent or long-term impact. Examples include vision or hearing impairments, physical disabilities, chronic illnesses, emotional disorders (e.g., depression, anxiety), learning disorders, and attention disorders (e.g., ADHD). If you have a disability which impairs your ability to complete this course successfully, please contact the University Accessibility Center (UAC), 2170 WSC or 801-422-2767 to request a reasonable accommodation. The UAC can also assess students for learning, attention, and emotional concerns. If you feel you have been unlawfully discriminated against on the basis of disability, please contact the Equal Opportunity Office at 801-422-5895, eo_manager@byu.edu , or visit https://hrs.byu.edu/equal-opportunity for help.
Inappropriate Use of Course Materials
All course materials (e.g., outlines, handouts, syllabi, exams, quizzes, PowerPoint presentations, lectures, audio and video recordings, etc.) are proprietary. Students are prohibited from posting or selling any such course materials without the express written permission of the professor teaching this course. To do so is a violation of the Brigham Young University Honor Code.
