摘要: SUMMARY The overall project objective is to develop an integrated, hierarchical design tool for simulation of unsteady flows and prototyping flow control strategies in high-speed combustors. software will make use a environment that allow full accounting the interaction sensor-controller-actuator-combustor dynamics, active loop. In Phase I we have developed proof-of-concept version such tool. combustor its components as sensors, actuators system are treated collection interacting coupled by computational environment. can be represented or reduced scale models allows mixed dimensionality simulations. This part research was synergized with another whose focus on modeling novel combustion systems. contains number strategy implementations ranging from model-based indirect model-free direct control. During applied latter approach demonstrated capabilities controlling isolator unstart hypersonic combustor. Full-scale performed using CFD-ACE+, high fidelity multiphysics CFD code originally at CFDRC. We verified CFD-ACE+ against density-based FASTRAN, regime interest capable correctly interest. integrated into aid Application Programming Interfaces (APIs). A graphical “drag-and-drop” component specification connectivity. successfully oversaw preliminary environment, API GUI development. consisted five basic tasks: 1) Adaptation Simulation Environment; 2) Refinement APIs; 3) GUI; 4) Code; 5) Demonstration controller Tasks 1-3 were done conjunction related propulsion Parts leveraged adapted this research.
