Medium Scale Testing of Furnace Chambers

In order to perform experimental research in advanced fire areas, it is necessary to have a fire test platform. In many cases this involves an extremely large capital investment, as for example the facilities at MSU and SwRI. At UT Tyler we are working with medium scale (~3-5 feet x 2-3 feet x 3-4 feet) temporary furnaces powered by venturi style burners.

Tests of Fire Compartment Window Boundaries

We are working to better characterize the behavior of windows in fire compartment boundaries. As these windows fail and fall out, the fire ventilation conditions change changing the fire energy evolution characteristics. We are combining thermal imaging and digital image correlation displacement measurements to study this issue. The first sets of images are from a large scale test for concept validation.

The second sets of images are from a test of a glass panel where the capabilities of digital image correlation and thermal imaging are shown to be strong compliments.
