Abstract: The field modelling technique is used to study the interaction of a sprinkler water spray with the fire-induced hot layer. The problem is divided into a gas phase and a liquid phase. Droplet trajectory is calculated by solving the equations of motion. Water droplet is assumed to be non-evaporating and only the source terms in the gas momentum and enthalpy equations of the air flow included in the interaction effects with water droplets. i.e. the 'Particle-Source-in-Cell' method. Predicted results include gas flow, temperature and smoke concentration field, the shape of the water spray and some relevant macroscopic parameters. The effect of mean droplet size on these parameters are shown. Water density received at floor level in cases with and without the fire are compared.
