Characterization of an Acetylene-Oxygen Flame for Material Studies on High-Temperature Materials

Abstract

Many experiment methods are possible for assessing the high-temperature performance of high-temperature materials, e.g., laser ablation testing, oxyacetylene torch testing, plasma wind tunnel testing, strip heater testing and scramjet testing. Oxyacetylene torch testing is the fast and economical method to assess the high-temperature performance of materials. In this regards, at the DLR Institute of Structures and Design, an oxyacetylene torch-testing facility has been established to perform high-temperature oxidation testing of UHTC materials such as CCSiC and UHT-CMC at temperatures up to about 2000 K. The purpose of the present work is to characterize the oxyacetylene burner flame and followingly, to make a statement about the thermal behaviours of the aforementioned materials in terms of heat flux incident an the related temperture fields. The results verified numerically and experimentally will then lead to supervise the experimental facility efficiency.
