Nokia Arena, located in the heart of Tel Aviv, has everything you need to allow you to create an international level production: a large auditorium, a magnificent gallery and a huge outdoor plaza.

In the area of the arena there are events, conventions, and product launches for between 300 – 11,000 people. … Read More

PyroSim: ATF engineering analysis of a fire scenario resulting in a firefighter fatality.

Posted on July 20th, 2012

The video below presents the ATF Fire Research Laboratory’s Engineering Analysis of the fire that occurred at 30 Dowling Circle on January 19th, 2011. ATF Fire Protection Engineers were asked to utilize engineering analysis methods, including computer fire modeling, to assist with determining the route of fire spread and the events that led to the firefighter MAYDAY and subsequent Line of Duty Death of Firefighter Mark Falkenhan.

Water Spray Interaction with Dense Gas Clouds

Posted on May 7th, 2012

Submission by: Robert N. Meroney, PhD. Wind Engineering Software, and Civil and Environmental Engineering, Colorado State University, Fort Collins, CO., USA

Water spray curtains can provide an effective and rapid dilution mechanism for low lying dense clouds.  Frequently such clouds are released as a result of a chemical manufacturing, storage or gas transportation accident.

Extensive field and laboratory tests have been performed to determine how well water curtains can mitigate actual spill conditions.  Numerical methods are often proposed to provide system design or timely response information, but most of these models reduce mathematical and computational complexity by integrating the equations of motion over volumes, sections or depths which provides computational speed but often sacrifices mixing detail and typically presume the use of empirical entrainment relationships.

Dambovita Center, Bucharest, Romania

Posted on April 1st, 2011

Submission by: Donna Netanel from S. Netanel Engineers and Consulting Ltd and OffStream Studios.

Plaza Centers has entered into a public-private partnership agreement with the Government of Romania to develop the Dambovita Center (known as Casa Radio) (Forum with Additional Images) in Bucharest, the largest development plot available in the city centre.” [Quote from this Forum with links added by Thunderhead]

The image and models below, created by Donna and Offstream Studios, show a view of the PyroSim model at the top and two Smokeview renders of the Fire Dynamics Simulator (FDS) simulation.  With the excellent use of obstruction transparency and colors, it is easy to visualize smoke movement within the volume of the building.

Vehicle Ferry

Posted on August 26th, 2010

Submission by: Craig Hofmeister, Rolf Jensen & Associates

A new 362-foot passenger and vehicle ferry vessel is under development and will include capacity for up to 1500 passengers and 144 vehicles. The vessel will include two vehicle decks with accommodations ranging from small passenger cars to larger freight and large goods trucks. RJA provided fire modeling services to assess smoke production and smoke movement from various car and truck design fire scenarios as part of an assessment to review occupant egress conditions throughout the vehicle decks. The fire modeling was also used to assess the thermal impact on the deck resulting from the large design fire scenarios.

The Welcome Pavilion, Yas Island Retail, Abu Dhabi

Posted on August 26th, 2010

Submission by: Jason Pritchard, Mott MacDonald

The Welcome Pavilion is the main entrance to a 300,000 sq m retail mall in Abu Dhabi. Mott MacDonald provided fire modeling services for the development. The purpose of the study was to trial proposed smoke extract designs – the aim being to keep smoke above head height indefinitely, giving occupants ample time for escape.

Binyaney Ha’uma Railway Station and Tunnel

Posted on August 26th, 2010

Submission by: Alex Kline, Rolf Jensen & Associates

The Binyaney Ha`uma Railway Station and Tunnel is the underground portion of a commuter subway system that will connect Tel Aviv to Jerusalem, Israel. The tunnel is approximately 1 mile long and terminates at the passenger station which will be located approximately 200 feet below the streets of Jerusalem. RJA provided fire modeling services for the entire railway station and tunnel to assess the impact a train fire developing in either the station or tunnel on the proposed smoke control system.
