Fibre orientation and the conduction of heat by a gas enclosed in ceramic layers
Abstract
Fibrous layers are an essential constituent of future heat protection systems. The conduction of heat by a gas enclosed in fibrous layers depends on layer and fiber density, mean fiber diameter and fiber orientation. Consideration of fiber orientation improves the correlation between model predictions and experimental results. It also permits a better explanation of the pressure dependence of convective heat transport.
