Computational Fluid Dynamics Enhancements for Scramjet Flow Simulations

Several high-fidelity computational schemes and turbulence-combustion interaction models, including the option for high-order spatial and temporal calculations, are proposed to significantly improve the accuracy and turnaround time for practical scramjet engine design and performance analysis. The proposed enhancements of existing tools, such as the government-owned VULCAN computer program, focus on accuracy, speed of execution, and general user interaction with the tools. The project targets issues associated with physics-based modeling of supersonic combustion, aerodynamics, turbulence, and their interactions, with the overall goal of providing accurate and computationally affordable tool. To develop the proposed software, TTC Technologies, Inc. (TTC) is leveraging its extensive experience in the relevant research for the topic and in developing truly advanced computational fluid dynamics (CFD) solutions at all speeds (subsonic, transonic, supersonic, and hypersonic). TTC will also partner with ATK GASL, Inc., who will provide quality data to validate the proposed tool, and leverage its extensive research and realistic scramjet manufacturing experience.
