Numerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
متن کاملActive Noise Control Using Glow Discharge
First-day spacecraft failures frequently occur as a result of the loads experienced during launch into orbit. These loads include structural vibrations transmitted at points of structural contact, and structural-acoustic vibrations created by the excitation of the payload fairing cavity. Structural control techniques, using piezoelectric actuators, have previously been studied as cost-effective...
متن کاملStudy on the Ionic Bombardment in a Glow Discharge Lamp
The surface of copper alloys was studied by means of a scanning electron microscope after having been sputtered by a glow discharge source under typical conditions for spectrochemical analysis. The surface topography developed during the process of sputtering gave the following two results: It would appear that the energy spread of the bombarding ions is small and the variation in the angles of...
متن کاملGlow Discharge Depth Profiling a Powerful Analytical Technique in Surface Engineering (TECHNICAL NOTE)
A variety of analytical techniques have been developed and employed to characterize the surfaces, subsurfaces and interfaces of surface engineering systems. They provide important information for quality control, process optimization and further development. Since the mid 1980's, glow discharge spectrometry (GDS) has emerged as an important and versatile technique for rapid depth profiling anal...
متن کاملEmission spectroscopic study on gas-gas interactions in glow discharge plasmas using several binary gas mixtures.
Emission spectra of constituent gas species from glow discharge plasmas using argon-helium, krypton-helium, argon-krypton, and krypton-argon gas mixtures were analyzed to elucidate collisional energy transfer between these gas species occurring in the plasma. In the argon-helium mixed gas plasma, the enhancement or quenching of particular Ar II lines was observed when helium was added to an arg...
