| 摘 要： | 本文给出了碳/碳复合材料热化学烧蚀对层流和湍流电离边界层影响的计算方法。边界层中考虑了20个气体组元,并假设所有化学反应平衡。应用了边界层方程的新解法和简化的输运性质处理。算例表明,烧蚀对边界层的电离特性有很大影响,烧蚀产物中,碱金属的电离并不总占优势。

| Abstract: | A calculation method for carbon/carbon composition ther-mochemical ablation effects on ionized laminar and turbulent boundary layers is given. In the boundary layers 20 gas species are considered and all chemical reactions which occured in them are assumed to be equilib-rium. The new solving method for boundary layer equations and simple disposal for transport properties are applied. The calculation examples indicate that ablation has great effects on ionization properties of the boundary layers and that ionizations of the alkaline metals are not al-ways dominant. |
