Investigation of Hypersonic Nozzle Flow Uniformity Using NO Fluorescence
ثبت نشده
چکیده
Planar laser-induced fluorescence visualisation isused to investigate nonuniformities in the flow of a hyper-sonic conical nozzle. Possible causes for the nonuniformityare outlined and investigated, and the problem is shown to bedue to a small step at the nozzle throat. Entrainment of coldboundary layer gas is postulated as the cause of the signalnonuniformity.

AIAA 2002-2917 Nonintrusive Temperature and Velocity Measurements in a Hypersonic Nozzle Flow
Distributions of nitric oxide vibrational temperature, rotational temperature and velocity have been measured in the hypersonic freestream at the exit of a conical nozzle , using planar laser-induced fluorescence. Particular attention has been devoted to reducing the major sources of systematic error that can affect fluorescence temperature measurements, including beam attenuation, transition s...
متن کاملIntegration between Measurements and Particle Simulations for Hypersonic Rarefied Flows
The hypersonic rarefied wind tunnel has lately been developed at JAXA. The characteristics of hypersonic rarefied flows have been investigated experimentally and numerically in this work. Using a sphere pendulous model, the test flow has been probed by measuring its displacement due to the aerodynamic force. In addition, a spatial variation of total pressure of the test flow has also been measu...
متن کاملThe role of gas dynamics in operation conditions of a Pulsed Microplasma Cluster Source for nanostructured thin films deposition.
This study intends to explain the fluid dynamic characteristics of a Pulsed Microplasma Cluster Source (PMCS). An axially symmetric steady state simulation is performed for modeling the real-life three-dimensional unsteady flow of hypersonic helium inside our PMCS. Hypersonic helium flow is simulated using Realizable k-epsilon turbulent model. We obtained the jet velocity, density, and pressure...
متن کاملInviscid Design of Hypersonic Wind Tunnel Nozzles for a Real Gas
A straightforward procedure has been developed to quickly determine an inviscid design of a hypersonic wind tunnel nozzle when the test gas is both calorically and thermally imperfect. This real gas procedure divides the nozzle into four distinct parts: subsonic, throat to conical, conical, and turning flow regions. The design process is greatly simplified by treating the imperfect gas effects ...
متن کاملFuzzy Assisted PI Controller with Anti-reset wind up for Regulating Pressure in a Hypersonic Wind Tunnel
Wind tunnels are being used to study the aerodynamic properties of race cars, fighter planes etc. It allows us to make a reusable prototype and test it in the tunnel. Hypersonic wind tunnels operate at hypersonic speeds ie, with a mach number greater than 6. For doing experiments, it is necessary to maintain a constant pressure in the settling chamber of the tunnel so that we get the desired Ma...
