Influence of solid constituent properties on thermal response of porous materials under shock loading
POSTER
Abstract
The heat output is determined using high speed pyrometry for various powders under shock loading in the present work. The pyrometry data for copper and silica powders, obtained in earlier work, are complemented with data for an iron powder. Comparison of the data for the three powders shows an unusually high heat output for the iron powder. However, the two-phase constitutive CTH modelling reveals a link of this higher output with particle size. Calculations for the powders with similar particle sizes demonstrate that the heat output for the iron powder lies between that for the copper and silica powders. This agrees with the inter-phase heat fluxes substantiated by the thermal properties of the condensed constituents.
