A wind tunnel test campaign was conducted, which campaign provided a couple of new knowledge to identify the cause of stagnation heat flux augmentation observed under high-enthalpy and high pressure condition in several major shock tunnels. The test was carried out in the free-piston high-enthalpy shock tunnel HIEST under the stagnation enthalpy from H(exp 0)=8MJ/kg to H(exp 0)=20MJ/kg with stagnation pressure P(exp 0)=50MPa. A flat plate for surface heat flux measurement was applied in the test campaign, on which plate surface, miniature coaxial thermocouples were instrumented. To measure radiation, but convection heating, optical windows were placed in the front of the thermocouples, which windows were acted as optical filters with different transparent wave length. The test results revealed that there was significant radiation heating on wavelength from visible to infrared, which heat flux was approximately up to 40% of total heating. It was concluded that the remarkable radiation was one of the main causes of the heat flux augmentation. Moreover, through the comparison between heat flux records with and without optical filters, it was found that the heat flux raise-up timing with optical filter was remarkably delayed from that of without optical windows. It was also concluded that the radiation was mainly emitted from the shock layer. |
