Advanced Chemistry and Physics of Fire

Recommended Prerequisites

2^nd Cycle concluded. Mathematical Analysis I, Mathematical Analysis II, Mathematical Analysis III, Physics I, Physics II, Thermodynamics, Applied Thermodynamics, Heat Transfer I, Heat Transfer II, Fluid Mechanics I, Fluid Mechanics II, Fundamentals of Fire Safety in Buildings.

Teaching Methods

Lectures

The methodology followed in the lectures consists first to motivate the student to study the subject to be presented and secondly to present the subject in an understandable way for the student. The presentation of the class is done using audio-visual media in digital format such as the projection of images and movies and supported in the bibliography.

Theoretical and Practical

The methodology followed in theoretical and practical classes consists in solving theoretical and practical problems carefully chosen to allow after their solving to reach an interesting conclusion and as general as possible. Conduction of two numerical simulation experiments. At the end of the course each student will make a synthesis work about the subjects treated in the lectures, and will make a critical analysis about the state of these knowledge.

Learning Outcomes

In this course, to be attended by students wishing to develop thesis in fields related to the modelling of fire development, will be transmitted complementary but also deeper knowledge to the one transmitted in the course Fundamentals of Fire Safety in Buildings and it will be developed the capability to develop simulation models of fires in buildings. It is intended that the students acquire a solid background in these areas so that they can understand in depth the phenomenon of fire and be able to develop a simulation model of fire in buildings. The areas of expertise to develop and implement which are the foundations of the science of combustion are thermochemistry, the processes of heat, mass and momentum transfer in laminar and turbulent regime, fluid mechanics and chemical kinetics.
