SR206 Heat flux measurements: Experiments and modelling (2018)

This report was prepared during research into the use of plate thermometers for heat flux measurements and how these measurements can subsequently be used in terms of modelling and estimating other conditions or parameters.

Plate thermometers for estimating incident radiative flux were investigated using a range of experiments: cone calorimeter tests, furniture calorimeter tests using a burner or a mattress as the heat source and ISO room experiments also using a burner or a mattress as the heat source. A series of experiments in the ISO room were also performed with the door of the ISO room sealed off.

The results from these experiments and the subsequent analysis are summarised in this report. Overall reasonable agreement was found between Gardon gauge results and the estimates of incident radiative heat flux for steady sources of heat once the results of each type of instrument reached a quasi steady state or when the heat source was increased relatively slowly compared to a distinct stepped increase.
