Two-dimensional velocity-field measurement in a hypersonic gas flow over a cone using planar laser-induced fluorescence
نویسنده
چکیده
Planar laser-induced fluorescence (PLIF) of nitric oxide is used to measure a component of the velocity field for the Mach 7 flow around a cone. Velocities are measured in the freestream, shock layer, and the separated region behind the cone. The measurements are compared with computational fluid dynamics (CFD) codes. The comparison indicates that the CFD correctly predicts the flow over the forebody and in the expansion around the cone shoulder, but incorrectly predicts the location of the re-attachment shock.

Investigation of Shock Wave Interaction Using Laser-induced Iodine Fluorescence
Detailed measurements of flow behavior have been taken in a rarefied ‘slip-flow’ regime hypersonic flow (Mach 12) over a sharp edged flat plate with a circular-cylindrical appendage designed to produced shock wave interactions. The flat plate is presented parallel to the wind tunnel freestream to generate a weak shock which impinges on the nearly-normal cylinder bow shock wave. Tests were condu...

Planar laser-induced fluorescence (PLIF) images of nitric oxide (NO) in hypersonic flow over a wedge and a hemisphere are compared with a theoretical PLIF model. The theoretical PLIF images are based on computational fluid dynamics (CFD) models including a perfect-gas model and a nonequilibrium chemistry model. Two dimensional maps of the flow parameters generated by the CFD are used to predict...

An investigation is presented of Mach 12 flow over a wind tunnel model of a tether connecting an aerobraking spacecraft to an inflatable drag device. The study was undertaken to support numerical simulations employed in the design of a “ballute” (balloon-parachute) aerobraking device currently being developed by Ball Aerospace and NASA. The attachment point of the tether to the ballute is subje...
متن کاملAIAA 96-2236 Comparison of theoretical laser-induced fluorescence images with measurements performed in a hypersonic shock tunnel
Planar laser-induced fluorescence (PLIF) images of hypersonic flow over a wedge are compared with a theoretical PLIF model. The synthetic images, which include the effects of collisional quenching, are based on a perfect-gas treatment of the fluid mechanics, assuming frozen chemistry. We find very good agreement between the model and the experimental measurements.
