Performance Evaluation of Real-Time Image-Based Heat Release Rate Prediction Model Using Deep Learning and Image Processing Methods
Опубликовано 2025-07-01Предметы: “...HRR prediction...”Heat release rate (HRR) is a key indicator for characterizing fire behavior, and it is conventionally measured under laboratory conditions. However, this measurement is limited in its widespread application to various fire conditions, due to its high cost, operational complexity, and lack of real-ti...

HRR-Based Calibration of an FDS Model for Office Fire Simulations Using Full-Scale Wood Crib Experiments
Опубликовано 2025-06-01Предметы: Полный текстThis study deals with the simulation of office fires by combining large-scale experiments with nine wooden cribs and a carefully calibrated computer model. It shows how real fire conditions, reaching up to 800–1000 °C, could be reproduced experimentally. The numerical model was validated by comparin...
