In recent years, Government and industry have both documented considerable interest in developing reusable, long-life, liquid hydrocarbon fueled rocket engines. However, in order to design an engine with these characteristics, a more complete understanding of the fuels liquid-side fluid characteristics, while in engine regenerative-cooling channels, is needed. To add to this required understanding, experiments are currently being conducted at the Air Force Research Laboratorys High Heat Flux Facility HHFF, located at Edwards AFB, CA. The HHFF is designed to explore many fuel related rocket engine design considerations e.g., high aspect ratio cooling channels, various fuel thermal stability issues, material compatibility, heat transfer capability, effects related to dissolved oxygen or specific sulfur species contained within the fuel, etc. Recently, the Air Force has been studying RP-2 Ultra-Low Sulfur RP-1 in order to establish an accurate baseline for future experiments in the HHFF. These experiments were conducted using low overall heat transfer coefficients and wall temperatures. This paper will present and discuss the results of recent Air Force experiments at HHFF.
