摘　　要：本文对有泰氟隆烧蚀的化学非平衡粘性激波层流场进行了数值模拟。应用空间推进与总体迭代相结合的求解方法，采用１９组元、２９种反应的空气—泰氟隆化学反应系统，对化学非平衡粘性激波层流场与泰氟隆壁面烧蚀传热过程进行耦合求解，研究了平衡催化壁和非催化壁条件对粘性激波层烧蚀流场的影响。The chemical non equilibrium viscous shock layer flows over a teflon ablative wall are calculated numerically. The coupled solutions of the chemical non equilibrium viscous shock layer flows and the teflon ablative procedures are obtained through space marching and global iterations. The overall teflon air chemical system used consists of 19 species and 29 reactions. The effects of the equilibrium catalytic and the noncatalytic wall conditions on the ablative flows are discussed.
