An Investigation of the Mechanisms of Heat Transfer in Low-Density Phenolic-Nylon Chars.
Abstract
The heat transfer mechanisms in phenolic-nylon chars were investigated. In order to separate the effects of solid and gas conduction and radiation, the thermal conductivities of three phenolic-nylon chars having porosities of 0.79, 0.82, and 0.88 were measured in vacuum, nitrogen, and helium environments. The temperature range covered was from 400 deg F (477 deg K) to 1000 deg F (811 deg K). The pressure range was from 0.002 to 760 torr. The thermal conductivity increased on changing the environment from vacuum to either nitrogen or helium.
