Abstract

This work describes the continuation of the experimental and numerical investigation of instrumented munitions in an International Organization for Standardization (ISO) 20 foot intermodal container to characterize the thermal response of the storage area and munitions. The numerical model has the capability to validate broad trends observed in the experimentally collected data. For this investigation, data is being collected through a field experiment of the storage structure and inert munitions instrumented with thermocouples collocated with a weather station. Data from field experiments will be used to develop and validate numerical models. The numerical model will save time and resources in future investigations of the thermal exposure of munitions in storage as well as advance the understanding of the implications of selecting a long term storage environment. This work will contribute to the advancement of an understanding of the combined heat transfer of energetic materials in several packaged configurations by natural convection and radiation driven by wall temperatures in a 3-D enclosure with external heat transfer driven by forced convection and radiation that includes distributed internal solids with different surface emissivity and internal conductivity. This will then be validated with experimental results. The numerical model will have several characteristics including heat transfer to the enclosure (intermodal container) by solar radiation, conduction, and forced convection; heat transfer between the enclosure to the packaged energetic materials by radiation, conduction, and natural convection; distributed thermal energy storage in packages; and transient temperature of the enclosure walls as the temperature is driven by the path and intensity of the forced convection and radiation.
