Current Status of Gas/Gas Injector Research at AFRL
Abstract
A computational and experimental program of research in gas/gas injection has been initiated in support of staged combustion cycle engines such as the H2/O2 Integrated Powerhead Demo or a staged combustion hydrocarbon boost engine. The overall objective of this research is to develop a design methodology for gas/gas injectors. By taking the approach of using experimental measurements to anchor state-of-the-art flow codes, we gain confidence in their predictive capabilities. This in turn leads to a more efficient design process which results in significant sayings in full-scale development time and costs. This paper focuses on a computational methodology to efficiently, accurately, and robustly obtain high- fidelity solutions of combusting rocket engine flows to gain a knowledge and understanding of their features. To that end, simulations of a combusting, single-element, shear-coaxial, H2/O2 engine were performed to characterize its flowfield and to validate the CFD++ flow solver for this class of problems. Both steady and transient solutions are examined and compared to experimental data to help determine the accuracy of the code.
