Fire dynamics in open compartments. In 6th international conference on INTEGRITY-RELIABILITY-FAILURE. lisbon978-989-20-8312-4http://hdl.handle.net/10198/21759With the aim to increase fíre safety in open compartments, such as open car parks, some correlative models were used to test the ability to recover both dynamics and thermal characteristics ofa ceiling-jet flow. The flow occurs when the fire plume impinges the ceiling and develops in the radial direction ofthe fire axis. Both temperature and velocíty predictions decisive for sprinklers positioning, fire alarms positions, detectors (heat, smoke) position and activation times and back-layering predictions. This investigation deals with a parametric analysis using different fire events, fíre scenarios and correlative formulations (Alpert, Cooper, Heskestad and Delichatsios, Motevalli and Marks). An advance calculation method (CFAST) based on a two zone model fonnulation was used to compare the results.engOpen car parksCeiling jetCorrelative modelsTwo zone models (CFAST)conference object
