Research Abstract

In this research, we have investigated surface catalytic effect on thermal protection systems with a microwave-discharge type surface catalysis measurement system.
First, we have investigated saturation effect in two-photon absorption laser induced fluorescence to atomic oxygen with a flow reactor. When we want to neglect this phenomenon, we should set the laser power lower than 1000 J/m2.Therefore, we have applied TALIF to surface catalysis measurement system with 140J/m2 laser power. As a result, we found the pressure dependency of the catalytic efficiency and it decreased when the pressure increased.
