Te Papa Museum Investigation at FEMTC 2016

August 31, 2016
The Fire and Evacuation Technical Modeling Conference (FEMTC) is fast approaching, and several abstracts have been selected. Kevin Weller, a Fire Engineer at Beca, is joining many others in more than two days worth of technical presentations. Kevin will be presenting the challenges and discoveries of investigating the safety of a twenty year old museum. Read More...

Comparing FDS results to fire spill-plume calculations in BRE Annex D

August 4, 2016
The BRE guide Design methodologies for smoke and heat exhaust ventilation summarizes the advice available from the BRE Fire Research Station (UK)  to designers of atria and other buildings. Annex D of the BRE document compares different fire spill-plume calculation methods applied to a multistorey shopping mall. We compare Fire Dynamics Simulator (FDS) results to the calculations in Annex D.  Read More...

Critical Velocity in Tunnel Fires

May 17, 2016
Merve Altay contacted us with a tunnel model that was experiencing a numerical instability. He was simulating a set of experiments performed to evaluate the critical velocity in a tunnel fire. Answering his question eventually led to improvements in FDS and a better understanding of user applications of PyroSim/FDS.  Read More...

Modeling Jet Fans, Part 3: Car Park Simulation

April 11, 2016
In this post, we explore modeling jet fans to extract smoke from a car park using FDS. The jet fans are modeled using HVAC ducts with shrouds. Read More...

Modeling Jet Fans, Part 2: Validation using Experimental Data

April 11, 2016
It is not feasible to simulate full scale parking garages with such a fine mesh, even if multiple meshes are used. This post discusses ways it may be possible to use a larger mesh size and still obtain meaningful results. Read More...
