Ever wonder how scientists measure the intensity of a fire? Join us on this episode as we invite Dr. Matt Bundy from NIST. We discuss the intricacies of heat release rate, calorimetry, and how NIST is championing open data with their astonishing database.You can learn more about the database here: https://www.nist.gov/blogs/taking-measure/new-nist-fire-calorimetry-database-available-answer-your-burning-questionsAnd find the database here: https://www.nist.gov/el/fcdI've tried to make this conversation for everyone. If you never saw a calorimeter or have no idea how to measure fire, from this episode you will learn probably all you need to know. If you know everything about calorimetry, there is a ton of golden nuggets on how NIST runs their experiments, that are absolutely worth listening too.In the podcast episode, we start deciphering the art of measuring fire characteristics - from using heat flux gauges, oxygen and mass loss calorimetry and what are the challenges to each of them.  We then explore the NIST Fire Calorimetry Database, unveiling its evolution from a humble set of data to an open-access resource. Dr. Bundy shares invaluable insights into the development of this enriching database, which has metamorphosed into an extensive video collection system that records fire experiments. He also whets our curiosity about the potential expansion and collaborations lying on the horizon for this unique database. Rounding off our discussion, we delve into the inner workings of the hosting process of the NIST Calorimetry Database, its data storage methods, and how it facilitates easy access to experiments. We also glimpse the future of fire studies as Dr. Bundy calls on the Fire Science Show community to suggest objects to burn for their calorimetry.
