Abstract: We report in this paper numerical studies on the interaction between a sprinkler water spray and a natural smoke extraction venting inside a building. This is carried out using the technique of building fire field modelling. A system of partial differential equations describing conservation of mass, momentum and enthalpy is solved numerically. The fire-induced air flow can then be predicted three-dimensionally with turbulent effects described by the κ-ε model. The sprinkler is simulated by an imposed water spray with the shape and velocities of droplets specified. The natural venting is described by appropriate free boundary conditions and its interaction with the water spray can then be studied. Macroscopic parameters, such as the drag to buoyancy ratio, and the convective cooling rate are computed accordingly.
