On the use of natural and forced convection correlations in predictive CFD simulations of liquid pool fires Ghent University
Numerical simulations of oscillatory combustion and extinction of a liquid pool fire in a reduced-scale and mechanically-ventilated enclosure Ghent University
The paper presents a numerical study on an 18 cm-diameter liquid pool fire in a reduced-scale and mechanically-ventilated enclosure. The enclosure walls are made of a calcium silicate layer and a steel layer on five sides, the remaining sidewall is made of heat-tempered glass. The ventilation system is extracted mechanically with free air inlet. Three air renewal rates (ARR) and open atmosphere conditions are considered in the numerical study. ...
Cost-optimization based generalized target reliabilities for reinforced concrete slab exposed to fire Ghent University
Risk-based design of structures can be based on lifetime cost-optimization, which involves balancing the future costs with the benefits of safety investments. However, such calculations are impractical for most individual projects due to complexity and computational challenges. In normal design conditions, the explicit cost-benefit assessment has been replaced by pre-calculated maximum levels of failure probability (i.e., target reliability ...
Evaluation of OpenFOAM’s discretization schemes used for the convective terms in the context of fire simulations Ghent University KU Leuven
Numerical analysis of a water mist spray : the importance of various numerical and physical parameters, including the drag force Ghent University KU Leuven
A comparative study on the effect of natural and forced convection correlations on the CFD simulation results of liquid pool fires Ghent University
The paper presents a detailed analysis of predictive numerical simulations of liquid pool fires, i.e., a 1 m – diameter methanol pool fire and a 0.7 m × 0.8 m ethanol pool fire. The burning rate is predicted using the ‘film’ model, including empirical correlations for heat and mass transfer. Although the forced convection approach (used for instance in the Fire Dynamics Simulator, FDS) yields relatively good results in terms of fuel evaporation ...
Analysis of adaptive mesh refinement in a turbulent buoyant helium plume Ghent University KU Leuven
Preliminary study of chemistry solvers with focus on ignition in the context of turbulent buoyancy-driven reacting flows Ghent University
Exploratory comparative study of the impact of simplified finite-rate chemistry in LES-EDC simulations of the UMD line burner Ghent University
This study focuses on incorporating finite-rate chemistry in turbulent combustion modelling in CFD simulations of the UMD line burner, a scenario considered to be representative of fire-induced flows. In this exploratory research, the use of EDC (finite rate chemistry) is compared with predictions obtained with EDM (infinitely fast chemistry) and validated against experimental data involving first and second order statistics. A sensitivity study ...
