The paper "Fire Investigation Using Computer Modelling" is a great example of management coursework.   The advent of computer modelling has taken the practice of fire and explosion investigation to another level. The invention of state-of-the-art equipment and strategies has gone a long way in improving the effectiveness and accuracy of virtually all fire and explosion investigations. The use of computer modelling in these activities has seen a major breakthrough in this field. One of these achievements is the determination of the exact causes of fire breakouts and explosions just minutes after they have been extinguished.

Such significant steps in this sector have also contributed to a substantial decline in the number of intentional arsonists. Currently, a majority of fires occurring across the globe are accidental in nature, thanks to the use of computer modelling in the investigations. However, as much as the use of computer modelling in fire and explosive investigations has a good number of applications, it also has its own limitations. This essay will look at the potential applications and limitations of computer modelling to fire and explosion investigations. APPLICATIONS The Spread of Heat and Smoke Computerized fire models have indeed played a significant role in fire and explosive investigations.

This is because they have a wide range of applications in various aspects of the investigations. The applications mainly centre on determining the history of the fire and the explosion. First and foremost, these computerized fire models can be used to predict the spread of heat and smoke in any building in the event of a fire or an explosion. The models are in a position to predetermine the direction of heat and smoke in a building of any design. Examples of computerized fire models that are capable of predicting the direction of heat and smoke in a building in the case of a fire or explosion are the Computational Fluid Dynamics (CFD) models (Drysdale, 1999).

This type of models works by solving certain fundamental equations associated with fire. The solved equations result in description and insight into the fluid flow and heat transfer phenomena of the fire. The determination of these two properties is the key to determining the direction of heat and smoke movement in a building in the event of a fire or an explosion. The prediction of the movement of heat and smoke in a building on fire can help in investigating the actual cause of the fire and explosion.

By knowing the direction of movement of the smoke and heat, the investigators will be able to determine its direction of origin and hence the point from where it started. The knowledge of this place will, in turn, help the investigators to establish the real cause of the fire or explosion.

Therefore, computerised fire models are crucial because they give hints that enable investigators to arrive at the exact cause of a fire breakout and explosion. The CFD models have recently become popular because they can be coupled with the modern performance-based codes to ensure an ambience of effective fire safety engineering (Babrauskas, 1995).
