Measuring thermal diffusivities of high explosives by the flash method. [LX-04, LX-07, LX-09, LX-10, LX-14, and RX-03-BB]
The purpose of the investigation was to examine the two-layer flash method for measuring thermal diffusivities of high explosives. The flash method was applied to LX-04, LX-07, LX-09, LX-10, LX-14, and RX-03-BB. Thermal diffusivities, measured over a temperature range 21 to 160/sup 0/C, varied from 0.0015 to 0.0041 cm/sup 2//s. Although the data values are higher than those previously published for explosives, the results on Teflon, stainless steel, and fused quartz correlate within 5 to 10% of published data. Additional work is needed to include analytically the contribution of heat loss to total error.
