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.


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.


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 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.


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.


Grades for the course will be based on the following distribution:

Grade scale: A ≥ 95%; A- ≥ 90%; B+ ≥ 87%; B ≥ 83%; B- ≥ 80%; etc.

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:

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 my own 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 Sexual Harassment

Title IX of the Education Amendments of 1972 prohibits sex discrimination against any participant in an educational program or activity that receives federal funds. The act is intended to eliminate sex discrimination in education. Title IX covers discrimination in programs, admissions, activities, and student-to-student sexual harassment. BYU’s policy against sexual harassment extends not only to employees of the university, but to students as well. If you encounter unlawful sexual harassment or gender-based discrimination, please talk to your professor; contact the Equal Employment Office at 422-5895 or 367-5689 (24-hours); or contact the Honor Code Office at 422-2847.

Students with Disabilities

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 Employment Office at 801-422-5895, D-285 ASB 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.
