A simplified analytical approach for the clear height in compartment fire based on a two-layer zone model

Chi Honn Cheng et al.

Summary: Compartment fire is an important research area in fire science and fire safety. The zone model is a simple and effective method for studying compartment fire. The differential equations based on a two-layer zone model have no analytical solutions, and numerical methods are required for solving them. However, in some special cases, analytical solutions for certain variables can be obtained. The method proposed in this study shows good agreement with experimental results in predicting smoke layer height.

A Global Model for Heat Release Rate Prediction of Cable Burning on Vertical Cable Tray in Different Fire Scenarios

Xianjia Huang et al.

Summary: This study develops a model for accurately estimating the heat release rate (HRR) of vertical cable tray fires, taking into account the effects of cable spacing, number of cable trays, and confined room. The model is based on bench-scale cable burning tests and shows lower prediction errors compared to previous models in the literature.

Fire spread along vertical greenery systems from window ejected flame: A study based on a fire dynamic simulator model

Tharindu Lakruwan Wickremanayake Karunaratne et al.

Summary: Recent studies have shown that poorly maintained vertical greenery systems (VGS) have a high fire risk and a tendency to cause very high heat release rates (HRR) in a case of fire. This study used numerical fire simulations to investigate the fire spread along a VGS and found a negative correlation between the fire spread rate and the moisture content and packing ratio of the vegetation.
