Abstract
To achieve accurate and fast temperature field prediction in large-space building fires, a fusion method is developed, which combines a developed physical model based on heat transfer as well as physical characteristics and an improved multiple moth-flame optimization. The artificial intelligence-based method has advantages like real-time prediction, physical explanations, and no prior data training. According to these advantages, the method can meet the real firefighting application requirements. Supported by two numerical cases of temperature predictions in a large underground parking fire and a large logistics warehouse fire, the results support that the developed method is effective and superior to the traditional moth-flame optimization algorithm and its variant. The developed fusion method of the physical model and multiple Moth-flame optimization can support an effective and useful tool to achieve quick temperature field prediction in large-space building fires for better fire rescue.
期刊介绍:
The International Journal of Thermal Sciences is a journal devoted to the publication of fundamental studies on the physics of transfer processes in general, with an emphasis on thermal aspects and also applied research on various processes, energy systems and the environment. Articles are published in English and French, and are subject to peer review.
The fundamental subjects considered within the scope of the journal are:
* Heat and relevant mass transfer at all scales (nano, micro and macro) and in all types of material (heterogeneous, composites, biological,...) and fluid flow
* Forced, natural or mixed convection in reactive or non-reactive media
* Single or multi–phase fluid flow with or without phase change
* Near–and far–field radiative heat transfer
* Combined modes of heat transfer in complex systems (for example, plasmas, biological, geological,...)
* Multiscale modelling
The applied research topics include:
* Heat exchangers, heat pipes, cooling processes
* Transport phenomena taking place in industrial processes (chemical, food and agricultural, metallurgical, space and aeronautical, automobile industries)
* Nano–and micro–technology for energy, space, biosystems and devices
* Heat transport analysis in advanced systems
* Impact of energy–related processes on environment, and emerging energy systems
The study of thermophysical properties of materials and fluids, thermal measurement techniques, inverse methods, and the developments of experimental methods are within the scope of the International Journal of Thermal Sciences which also covers the modelling, and numerical methods applied to thermal transfer.
