Undergraduate Course: Fire Dynamics Laboratory 5 (CIVE11023)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 11 (Year 5 Undergraduate)
||Availability||Available to all students
|Summary||This course consists of a series of laboratory sessions that will introduce the student to a variety of different experimental techniques of relevance to fire safety engineering. Each session will be introduced with a guide to relevant theory with the aim of providing the students with the fundamental knowledge to support understanding and interpretation of the experiments, as well as a safety briefing and guide to risk assessment. The use of standard tests and the application of the results to design will be emphasized.
1. Solid fuel ignition (4 hours)
This is the first of two laboratory demonstrations conducted to illustrate the different processes leading to ignition of combustible materials and is intended to provide insight on the ignition phenomenon.
- Application of ignition theory
- Piloted, auto and spontaneous ignition
2. Liquid fuel ignition (4 hours)
This is the second ignition laboratory demonstration conducted to illustrate the use of ignition to establish flammability criteria.
- Flash point/fire point
- Physical processes and Standard tests
3. Reaction-to-fire behaviour of solids (4 hours)
In this laboratory, the cone calorimeter apparatus is used to examine the ┐reaction-to-fire┐ behaviour of solid fuels under different heat exposures, with specific attention to:
- Ignition time
- Subsequent energy release rate
From the measurements, the following parameters will be determined:
- Ignition temperature
- Thermal inertia
4. Flame spread (4 hours)
The physical mechanisms controlling flame spread will be described on the basis of a lateral flame spread test. The demonstration will emphasize the following aspects:
- Materials properties: influence of a material thermal and chemical properties on the rate of spread
- Orientation: upward, downward, horizontal, lateral.
- External heat flux
- Fuel thickness: thick:thin materials.
5. Fire plumes and calorimetry (6 hours)
The evolution of the burning rate and fire dynamics of fire plumes as a function of different parameters will be established, using open pool fires. Empirical and analytical formulations will be validated for various fire sizes with respect to characteristic parameters, i.e.:
- Centreline temperatures
- Entrainment rate
The effects of confining the fire within a compartment will also be examined and interpreted in relation to simple fire models.
