Introduction
The Fire Dynamics and Modelling course will follow a structured approach starting from the general fundamental principles of combustion flammability and heat transfer, and will lead you through to the more specific study of fire spread and fire development in compartments.
The principles of fire protection practice and technology will be discussed within the context of understanding the fire development mechanism and the response of structures to fires.
Your learning experience will be enhanced through theoretical examples and brief problems that you’ll be asked to attempt on your own or in groups.
Course Objectives
On completion of this course, you should:
- be able to apply general combustion and engineering principles to fires
- know the parameters that influence flame spread and steady burning and be able to quantify the burning rate in compartment fires
- predict the rate of development of the fire, the onset of flashover, and appreciate the application of these concepts to fire protection design
- understand the factors influencing smoke toxicity and movement
- be aware of the predictive tools that are available and become familiar with the application and use of such tools, through ‘hands-on’ practice.
Target Audience
This course is for you if you wish or need to gain a comprehensive, scientifically-based analysis and engineering quantification tools, of fire development and consequence assessment in industrial and residential scenarios.
Perhaps you’re involved in the design and operation of buildings and chemical plant (architect, civil engineer, chemical engineer) or in the design of protection systems (passive and active system developer, manufacturer, installer).
Maybe you’re responsible for building and plant safety on a day-to-day basis, a regulator or adviser (Health and Safety Executive, Fire Service, Home Office, local authority, building control office, consultant, insurer) or firefighting professional.
This course would also be very useful if you’re a new researcher in the field.
