Improved Hypersonic Jet Interaction Modeling with Propulsion Exhaust

For hypersonic glide vehicle (HGV) and hypersonic cruise missile (HCM) engagement scenarios intercept occurs in a flight regime where aerodynamic interaction and chemical reacting flow effects are large. To support the development of HGV and HCM intercept vehicle concepts, this program extends a current state-of-the-art hypersonic flow solver and modeling toolkit, Reentry Vehicle Flowfield 3-D Model (RVFM3D) for application to hypersonic, reacting flow jet interaction (JI) problems. RVFM3D is a 3-D, automated flowfield modeling package specialized for hypersonic vehicle analysis that includes the advanced physical models of the CRAFT CFD(R) solver. It additionally includes: (1) a user-friendly interface to expedite problem setup, (2) an automated grid generator for the user specified vehicle body, and (3) an automated execution environment to efficiently complete and post-process the simulation. These automation features greatly reduce the total solution generation time and enable non-CFD experts to rapidly turn around vehicle simulations.
