    Abstract

    From theoretical considerations, a custom slug calorimeter heat flux transducer was developed for experimental use in the measurement of heat fluxes transferred through layers of fabric to the surface of a human mannequin during simulated flash fire conditions. This paper describes the determination of the transducer's physical size, its limitations and heat loss considerations, a computer simulation of transducer operation and the evaluation of transient heat flux measurements. The transducer's loss factors were predicted numerically and determined experimentally. The overall performance of the transducer was also examined under varying simulated applied heat flux input.
