Book Description
Natural fires can be considered as scale-dependant, non-linear processes of mass, momentum and heat transport, resulting from a turbulent reactive and radiative fluid medium flowing over a complex medium, the vegetal fuel. In natural outdoor conditions, the experimental study of natural fires at real scale needs the development of an original metrology, one able to capture the large range of time and length scales involved in its dynamic nature and also able to resist the thermal, mechanical and chemical aggression of flames on devices. Robust, accurate and poorly intrusive tools must be carefully set-up and used for gaining very fluctuating data over long periods. These signals also need the development of original post-processing tools that take into account the non-steady nature of their stochastic components. Metrology for Fire Experiments in Outdoor Conditions closely analyzes these features, and also describes measurements techniques, the thermal insulation of fragile electronic systems, data acquisition, measurement errors and optimal post-processing algorithms. This book is intended for practitioners as a reference guide for optimizing measurements techniques in an outdoor environment. Advanced-level students and researchers will also find the book invaluable.

Measurement of Temperature, Displacement, and Strain in Structural Components Subject to Fire Effects

ISBN: 9781496051424
Category : Technology & Engineering
Languages : en
Pages : 86
Book Description
For the last forty years, NIST has led the world in fire metrology through research conducted at the Large Fire Laboratory, which is being expanded to enable experiments on real-scale structures under combined structural and fire loads. The combined capabilities of large fire testing and structural fire testing will be comprised in the National Fire Research Laboratory (NFRL), which is expected to be completed in 2013. Measurements of temperature, displacement, and strain at hundreds of points on a structural system in the fire zone are needed to validate analytical tools for fire conditions. However, the ability to measure the performance of structures during realistic fire exposures is severely limited due to a significant gap in measurement science. At present, temperatures are measured with thermocouples and strains are measured with high temperature strain gages. Each of these sensors requires a separate line for data collection during the experiment. Further, high temperature strain gages are unreliable and often do not perform as expected during fire tests. Significant improvements to structural measurement in fire conditions are needed to advance the validation of analytical tools and performance based design methodologies. Candidate methods for temperature, displacement, and strain measurements that could meet these performance requirements were reviewed. A demonstration test that employed a natural gas burner in the Large Fire Facility evaluated the potential of digital image correlation and high temperature strain gages to measure thermally induced strains.The technology review and the outcome of the demonstration test indicate that digital image correlation and fiber optic methods have great promise for temperature, displacement, and strain measurement. A four-stage development plan is proposed to overcome these challenges.
