摘要

空气作为飞行器热防护的常用冷却气体，其组分N

与O

在N

离解尚不显著的温度区间表现出明显差异的化学反应活性，厘清二者在高焓湍流边界层中的特性，对飞行器高焓工况下的工程实践具有重要意义。基于课题组自研的开源高精度化学反应湍流求解器OpenCFD-Comb，采用直接数值模拟，研究了来流马赫数10的高焓湍流平板边界层在完全湍流区通过狭缝注入O

后，各组分的演化以及化学反应与湍流的相互作用。模拟工况为吹吸比0.001，注入与来流温度相同的纯O

。结果表明：注入区域下游形成局部富氧带，导致O

呈现非单调分布，并显著促进了O的生成；O

与N

的质量分数脉动显著增强，而N与NO的质量分数脉动相对减弱；O

注入加强了O

、O、NO的化学反应，对不活跃的N

、N影响较小；此外，相对于质量分数脉动，湍流-化学耦合对温度脉动更为敏感。

Abstract

Cooling-gas injection is crucial to the thermal protection of hypersonic vehicles. As a commonly used coolant

air contains N

and O

which exhibit different chemical reactivities under temperature conditions where N

dissociation is not yet significant. Understanding their behavior in high-enthalpy turbulent boundary layers is of practical importance for vehicle thermal management under realistic flight conditions. Using OpenCFD-Comb

open-source high-order solver for chemically reacting turbulence developed by our group

direct numerical simulations are performed to investigate species evolution and turbulence–chemistry interactions in a Mach 10 high-enthalpy turbulent boundary layer over a flat plate

with O

injected through a slit in the fully turbulent region. Pure O

is injected at the free-stream temperature with a blowing ratio of 0.001. Results show that the injection creates a localized oxygen-rich zone downstream

leading to a non-monotonic O

distribution and significantly enhanced production of atomic oxygen. Mass-fraction fluctuations of O

and N

are amplified

while those of N and NO are weakened. The injection strengthens chemical reactions involving O

O and NO

but has limited effect on the relatively inactive N

and N. Compared with species fluctuations

turbulence–chemistry coupling is more sensitive to temperature fluctuations.
