Experimental surface heat flux measurement in hypervelocity flows
… in geometry on heat transfer. The Hypervelocity Expansion Tube (HET) is one of a few facilities in the US that are able to create these flows, and thus it is an optimal test bed for these types of studies. Two gage types used in order to measure surface heat transfer, thermocouples and thin film …

The role of aerothermochemistry in double cone and double wedge flows
… for shock wave boundary/layer interactions. An expansion tube is used to generate flows with enthalpies ranging from 2.2-8.0 MJ/kg (2-4 km/s) and Mach numbers from 4-7. The expansion tube is a novel impulse facility for accelerating a test gas to these velocities, while maintaining a minimally …

Post-shock thermochemistry in hypervelocity CO2 and air flow
… experiments are conducted in the Hypervelocity Expansion Tube (HET) which, by virtue of its flow acceleration process, exhibits minimal freestream dissociation in comparison to reflected shock tunnels. This simplifies the comparison with computational result as freestream dissociation and …

Modeling of no radiative emission in non-equilibrium hypersonic flow
… conditions used for the simulations are a shock tube and a cylinder in a Hypervelocity Expansion Tube (HET) experiment. The simulated HET conditions present a 2D flow field moving around the cylinder and presents several regions of interest including the bow shock and the expansion region. …

Modeling of shock boundary layer interactions and stability analysis using particle approaches
… compare with measurements in the Hypervelocity Expansion Tube (HET), Calspan-University at Buffalo Research Center (CUBRC), and T-ADFA free-piston shock tunnel facilities using particle approaches to model the Boltzmann equation. The Boltzmann transport equation is the most general formulation …
