Brown and Stephen E. Dunagan. Abstract. An experimental study of the axisymmetric shock-wave / boundary-layer strong interaction flow generated in the vicinity of a cylinder-cone intersection was conducted. The study data are useful in the. Interferometric synthetic aperture radar, abbreviated InSAR (or deprecated IfSAR), is a radar technique used in geodesy and remote geodetic method uses two or more synthetic aperture radar (SAR) images to generate maps of surface deformation or digital elevation, using differences in the phase of the waves returning to the satellite or aircraft.   The interaction between a shock wave and a boundary layer often leads to extremely detrimental effects, especially if the shock is strong enough to separate the boundary layer. When this happens, there occurs a rapid growth of the dissipative region along with a dramatic intensifying of turbulent fluctuations with the frequent occurrence of.

The results of a holographic interferometric and analytical examination of shock wave/turbulent boundary layer interactions occurring in a flow near a cone-cylinder intersection are reported. A Mach flow with an Re of 18 million was used, along with cone angles of , 20 and 30 deg. Negligible, incipient and large scale separations were.

Shock Wave–Boundary-Layer Interactions: Why They Are Important. The repercussions of a shock wave–boundary layer interaction (SBLI) occurring within a flow are numerous and frequently can be a critical factor in determining the performance of a vehicle or a .   Unsteadiness in transonic shock-wave/boundary-layer interactions: experimental investigation and global stability analysis 24 September | Journal of Fluid Mechanics, Vol. Development of a Dual-PIV system for high-speed flow applications.

Interferometry is a family of techniques in which waves, usually electromagnetic waves, are superimposed, causing the phenomenon of interference, which is used to extract information. Interferometry is an important investigative technique in the fields of astronomy, fiber optics, engineering metrology, optical metrology, oceanography, seismology, spectroscopy (and its . "A Holographic Interferometric Study of an Axisymmetric Shock-Wave/Boundary Layer Strong Interaction Flow," AIAA Paper , presented at AIAA 18th Fluid Dynamics and Plasmadynamics and Lasers Conference, Cincinnati, Ohio, July, A combined experimental and computational investigation of an axisymmetric turbulent shock-wave boundary-layer interaction flow is presented. Experimental measurements include both mean and fluctuating data obtained by LDV techniques and identify large scale unsteady motions associated with shock induced separation. Shock-wave boundary layer interaction (SBLI) is one of the most important phenomenon which occurs in supersonic inlets that will result in a very complicated flow structure, 3D .
