Application of a noisy data classification technique to determine the occurrence of flashover in compartment fires
This paper presents a hybrid Artificial Neural Network (ANN) model that is developed for noisy data classification. The model, named GRNNFA, is a fusion of the Fuzzy Adaptive Resonance Theory (FA) model and the General Regression Neural Network (GRNN) model. The GRNNFA model not only retains the important features of the parent models, which include stable learning, fast training, and an increm...
متن کاملThe 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 کاملNumerical experiments and compartment fires
Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. An alternative or complement to these often expensive and resource demanding traditional experiments are numerical experiments. In this paper, numerical experimen...
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...
