Advanced Diagnostics for High Temperature Distributed Combustion in High Temperature Energy Systems
Abstract
The proposed diagnostics will enhance the quality of research and research-related education. The outcome from the use of the proposed diagnostics tool will significantly enhance the quality of data obtained for improved understanding of the fundamentals in several elements of the current HiTES program. The data will be valuable in model validation and model development. Detailed knowledge on the flow, thermal and chemical behavior is critical to develop the revolutionary volume distributed combustion and other technologies in the program for higher efficiency, performance and low noise. The high intensity combustion examination is required in many power and propulsion conditions that are critically important in DoD. Understanding reaction kinetics and prevailing conditions to achieve distributed regime is critical to extend our fundamental understanding of the unique distributed green combustion at intensity. Evaluating the role of mixture preparation and how to achieve the required mixedness between air, hot reactive gases and fuel is of critical importance to develop high efficiency near zero emissions gas turbine combustors with focus on how to achieve adequate mixing through novel mixing techniques while benefiting from existing turbulence in the flow. Thermal field uniformity arising from such combustion regime along with combustion stability and combustion uniformity are expected to reduce the thermal load on turbine blades leading to much higher efficiency and longer turbine and engine life. The wide operational range exhibited by this combustion regime will allow combustor operation in high speed engines and dump combustors over much wide dynamic range and offer fuel flexibility without the presence of combustion instability and low noise. The comprehensive database to be obtained will provide a new direction for the mathematical modeling of distributed green combustion turbine as well as fuel reforming for enhanced hydrogen production.
