The role of thermal radiation on the initiation of flashover in a compartment fire
Importance of thermal radiation for transition to flashover in a compartment fire will be demonstrated. A one zone model is developed with the objective of capturing the key mechanisms responsible for the initiation of flashover, i.e. physics of flashover. Thermal radiation is shown to be a key point and the inclusion of a three-dimensional radiation model is essential in the development of an ...
متن کاملThe Effect of Thermal Radiation on the Dynamics of Flashover in a Compartment Fire
Flashover is a phenomenon describing a room fire changed from the growth stage to the development stage. There is a rapid increase in size and intensity. The radiant heat flux back to the fuel surface and the floor of the room is known to be one of the key parameters leading to flashover. Indeed, a heat flux (largely due to radiation) of 20 kW/m to the room floor is often taken to be the condit...
متن کاملOn the Equations for Flashover Fire in Small Compartments
Equations for studying flashover fire were studied experimentally in this paper. Experiments were carried out in a chamber inside a full-scale burning test hall of the joint project between The Hong Kong Polytechnic University and the University of Science and Technology of China. Three correlation equations on estimating the critical heat release rates for flashover were considered. The two-la...

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Predicting Rapid Fire Growth (Flashover) Using Conditional Generative Adversarial Networks
A flashover occurs when a fire spreads very rapidly through crevices due to intense heat. Flashovers present one of the most frightening and challenging fire phenomena to those who regularly encounter them: firefighters. Firefighters’ safety and lives often depend on their ability to predict flashovers before they occur. Typical pre-flashover fire characteristics include dark smoke, high heat, ...
