Tailored Supersonic Flow Fields

Corvid Technologies, in partnership with North Carolina State University (NCSU), propose to leverage our computational and experimental capabilities to design experimental technology to replicate supersonic fields of interest to the customer during Phase I. Some limited experimental work will be carried out to support Phase II planning as well. Distortion patterns representative of the flowfield aft of a supersonic jet inlet will be used as the target patterns to match during this effort. Corvid’s flexible grid generation methods, as well as our internally-developed computational fluid dynamics solver, will be used to model the experimental set up in the Air Force Research Laboratory (AFRL) ADAC facility to define the distortion generation techniques. The Design Analysis Kit for Optimization and Terascale Applications (DAKOTA) toolkit developed by Sandia will be used to drive the optimization process around RavenCFD in an attempt to automate and quantify how well the target distortion pattern is matched by the simulated experimental technique. NCSU’s high-fidelity LES/RANS CFD code, REACTMB, will be used to inform the CFD calculations carried out at Corvid.
