Evaluation of the Ability of Fire Dynamics Simulator to Simulate Positive Pressure Ventilation in the Laboratory and Practical Scenarios

Report Date: April 2006

Positive Pressure Ventilation (PPV) is used both to improve conditions during fire attack or after the extinguishment of a fire. It has proven to be a useful tool if used properly, but if used improperly it can worsen conditions and injure or kill firefighters and civilians. Using data from three full-scale PPV experiments, this NIST project evaluates the ability of the computational fluid dynamics based Fire Dynamics Simulator to accurately simulate the experimental results.

    The NIST Fire Research Division develops, verifies, and utilizes measurements and predictive methods to quantify the behavior of fire and means to reduce the impact of fire on people, property, and the environment. This work involves integration of laboratory measurements, verified methods of prediction, and large-scale fire experiments to demonstrate the use and value of the research products.

    Through its programs in measurement, prediction, systems integration, and the dynamics of fire and its interactions with the built and natural environment, the division provides leadership for advancing the theory and practice of fire safety engineering, fire fighting, fire investigation, fire testing, fire data management, and intentional burning.
