State-of-the-Art Fire Modeling Enables Innovative Solutions
The most widely used model for complex fire modeling needs is the NIST FDS (Fire Dynamics Simulator). FDS is a computational fluid dynamics (CFD) model developed specifically for modeling fire driven flows. FDS is routinely applied to a wide range of problems including performance-based design, fire reconstructions, test planning, codes and standards development, dispersion, and indoor air quality. JENSEN HUGHES’ experienced staff of engineers, scientists, and technicians have earned an award winning, worldwide reputation for the application of FDS to novel engineering problems. JENSEN HUGHES is proud to count amongst its staff a member of the FDS development team. This gives JENSEN HUGHES unparalleled insight into the application of FDS and the ability to guide FDS development to emerging applications.
Atria and Other Large Volume Spaces
Computer modeling of smoke movement in atria and other large open spaces such as stadiums, airport terminals, and malls, has the potential to refine smoke control system requirements to reduce cost and complexity. At JENSEN HUGHES, we typically make use of FDS to evaluate the problem.
Providing modern fire protection to existing historic structures is often a challenge. Adding modern systems to historic buildings can disrupt the historic fabric of the structure. Use of FDS can aid in designing fire protection systems that meet life safety and property protection requirements while minimizing harm to the historic nature of the building.
National Parks and Monuments
National parks and monuments provide unique challenges to fire protection. Remote locations, adverse weather conditions, and beloved historic structures all pose challenges to fire protection design. Fire modeling with FDS quantitatively assess fire hazards and guides fire protection design. We used FDS to aid in the design of fire protection systems for the historic Awahnee Lodge in Yosemite National Park (shown).
Heavy industry, aerospace, and power generation facilities can pose significant hazards to employees and their off-site environs. We use FDS to provide assessments of the consequences of maximum hypothetical events.
Codes and Standards
The ongoing evolution of codes and standards requires a scientific, verifiable basis for changes. Skilled use of advanced models such as FDS can cost-effectively perform hundreds of numerical experiments to develop and verify changes to codes and standards.
