To start or not to start: that is the question
The BAM6QT is a hypersonic wind tunnel that was simulated with a 7-degree half-angle cone with diameters ranging from 4 to 7-inches, three different cone setups, and viscous and inviscid flow computations. These tests were then compared to determine what effects would cause the tunnel to unstart. …

A computational investigation of predicting wind tunnel results for selected hypersonic wing test structures
A CFD methodology for simulating various configurations of three selected wings in Purdue University’s Boeing Air Force Office of Scientific Research Mach 6 Quiet Tunnel (BAM6QT) is presented. The NASA-developed computational fluid dynamics (CFD) code, FUN3D, is used to calculate forces, moments, …

Sensitivity analysis and simulations of surface heating for hypersonic cavity flows
Hypersonic flow over cavities results in instabilities and discontinuities that affect the surface properties, and potentially results in surface damage. Simulations were performed using semi-structured 2D meshes in FUN3D with the Spalart-Allmaras and Menter Shear Stress Transport turbulence models …
