项目摘要
Coking phenomenon in low density carbon phenolic ablative material exposed to aerodynamic heating is examined experimentally. The in-depth density and gas permeability of the material heated in an arcjet wind tunnel is measured. Toward the surface within the char layer, the density increases and the gas permeability decreases respectively. The reason for such a trend is likely due to coking effect: coking in the char layer is known as a phenomenon that when the pyrolysis gas passes through the porous char layer to the surface, solid carbon is deposited within the char layer under the chemical decomposition reaction of hydrocarbon species such as CH4.It is find in this study that coking could occur in a low density carbon-phenolic ablator.
在实验中检查了暴露于空气动力学加热的低密度碳酚类烧蚀材料中的焦点现象。测量了在Arcjet风洞中加热的材料的深度密度和气体渗透性。朝向炭层内的表面,密度增加,气体渗透率分别降低。这种趋势的原因很可能是由于焦化作用而引起的:炭化层中的焦化被称为一种现象,即当热解气体通过多孔炭层穿过多孔炭层到达表面时,在该研究的化学分解反应中,固体碳被沉积在char层中,例如CH4。
