The heat flux sensor (hereafter referred to as “Thermal Cube”) is a simple and effective device used to measure the thermal energy that is released during high heat load applications and that is incident on the sensor at a given location. The sensor uses a one-dimensional, finite-length scale, transient heat conduction model to estimate energy per unit area (in kW/m2) that is incident upon it.
The data obtained from the Thermal Cube will enable determination of the following:
· Transient heat flux
· Time to ignition (of vegetative fuels)
