Abstract
Based on the computational fluid dynamics (CFD) simulation software and its parallel techniques, the standard k-ε turbulent flow equations with additional buoyancy-modified, the PDF(Probability Density Function) non-premixed combustion model, and the discrete ordinates (DO) radiation model were used to simulate the kerosene pool fire scenarios of various pool diameters in stagnant air and in a cross-wind. Based on these simulations, the relationships between the pool size and the flame height and flame temperature were obtained, as well as the effective law of the wind speed change on the fire tilt angle. The results presented in this paper are of great significance in the hazard evaluation of the thermal radiation of the pool fire.
