The Patch Integral Method (PIM), a New Heat Transfer Analysis Tool for Hypersonic Wind Tunnel Facilities at NASA Langley
The NASA Langley Research Center hypersonic wind tunnels serve a vital role in the field of hypersonics in both helping validate CFD predictions and producing experimental results. These tunnels have been heavily utilized for decades by numerous planetary missions, such as MSL and Orion, commercial …

Hypersonic test facilities: requirements analysis and preliminary design
… interest in aerospace vehicles operating in the hypersonic regime. With this interest has come a need to not only reestablish the hypersonic test capability that was available in the 1960s but to enhance this capability to meet the demanding needs of today's proposed vehicles. This will require …

Estimation of Unsteady Nonuniform Heating Rates from Surface Temperature Measurements
… interactions are reproduced experimentally in hypersonic wind tunnels to study how the flow structures relate to the deleterious heat fluxes. In these studies, localized fluid jets created by shock interactions impinge on a test cylinder, where the temperature due to the heat flux is measured. …

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. …

AEROSOL EFFECTS IN HIGH SUPERSONIC FLOWS
… and carry significantly less risk, although wind tunnels can only replicate a subset of the conditions experienced in actual flight. One of these conditions that has not been adequately captured in wind tunnels is the effect of particulates in the atmosphere. Typical wind tunnels use a pure, …

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, …
