259-An Introduction to Heat Transfer in Structure Fires
Course Objectives: This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
Besides the fire triangle (fuel, heat, oxygen), heat transfer is the driving factor behind how fires start, grow, and potentially threaten life and property. This course provides and introduction to methods for calculating conduction, convection, and radiation which occur in a typical structure fire. Methods are presented for calculating temperatures and velocities in side of compartments during a fire and how to calculate the activation time for a sprinkler head. A brief introduction into modern computer fire models is presented and an excel file is included with the course material which has been programmed to complete the equations used in the course.
Upon completion of this course, participants will be able to:
- Describe the role heat transfer plays in structure fires.
- Use hand calculations and computer programs to estimate the heat flux to objects from a fire.
- Use hand calculations and computer programs to estimate the ignition time for objects based on a given heat flux.
- Use hand calculations and computer programs to estimate the temperature inside of structures containing a fire.
- Describe the different kinds of computer fire models and their limitations.
