2 Fires and Smoke Movement ANSYS CFD is used by many companies for smoke movement assessment Characterised by complex geometries Large atria, underground stations (Crossrail) Pre-fire ventilation CFD analysis Jet fans and other fire/smoke mitigating devices required in the analysis Transient change in topology and other complex behaviour Window breaking as heat from a fire spreads through a double skin façade 2010 ANSYS, Inc. All rights reserved. 2 ANSYS, Inc. Proprietary
3 Fires and Smoke Movement ANSYS CFD has two methods Inert simulation Add a source of heat and smoke to a 3D volume representing the fire Efficient Assumes flame shape Reacting simulation Add a source of fuel vapour over a 2D surface Equations for reactants and products Predicts the flame shape Required if strong interaction with ventilation flow Can easily switch between techniques as required 2010 ANSYS, Inc. All rights reserved. 3 ANSYS, Inc. Proprietary
4 Smoke Management Fire scenario with smoke penetrating many occupied areas of a building with a complex atrium Fire scenario with a smoke management system that segregates the atrium In RWDI s experience, providing a code specified quantity of exhaust at the top of the atrium is not always sufficient for a safe atrium design. Other design strategies are necessary to help keep smoke out of the occupied zones, and RWDI uses a number of these to improve smoke management systems. For example, an atrium can be segregated into smaller and simpler atria when a fire erupts. Segregation in this particular atrium led to measurable reductions in undesired smoke propagation, used less than half the exhaust air, and saved the owner both capital and operating costs.
