Experimental study of nose-tip bluntness effects on hypersonic boundary-layer transition in a shock tunnel [PDF]

open access: yesScientific Reports
This study experimentally investigates the effects of nose-tip bluntness on boundary-layer transition over a $$7^\circ$$ 7 ∘ half-angle cone at Mach 6.76, using the Seoul National University Hypersonic Shock Tunnel.

A Visualization of Ultrasonic Beam from a Medical Transducer using a Combination of Background-Oriented Schlieren Imaging with Hilbert Transformation

open access: goldJIF (Jurnal Ilmu Fisika)
Ultrasonics in the medical field require a safe treatment for patients. The uncontrolled intensities of the ultrasonic waves cause ineffective treatment. So far, the hydrophone probe provides a standard for ultrasonic visualization. However, this method

Post-Processing of Schlieren Images [PDF]

open access: yesINCAS Bulletin, 2021
In general, the Schlieren visualization method is used to qualitatively describe phenomena. However, recent studies have attempted to convert the classical Schlieren system into a quantitative method to describe certain flow parameters.

Computerized Schlieren visualization [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1986
In everyday scientific research, the sought information about the acoustical phenomenon under study is often conveyed by the beam profile, or more generally, by the spatial distribution of the acoustic field. In many cases, such as Rayleigh phenomena, diffraction, scattering, leaky surface wave, etc., the acoustic field of interest can be observed ...

Flow visualization techniques, new developments and modernization of the existing Schlieren system in the Trisonic Wind Tunnel [PDF]

open access: yesINCAS Bulletin, 2011
Schlieren flow visualization methods are an important part of high speed wind tunnel testing, being a fast and reliable method of graphically presenting complex dynamic phenomena that occur in high subsonic, transonic and supersonic regimes.

A - a view in the invisible [PDF]

open access: yesTheoretical and Applied Mechanics, 2013
Flow visualization is an important topic in, experimental and computational fluid dynamics and has been the subject of research for many years. This paper presents an overview of flow visualization techniques. The physical basis and applications

State of the art of quantitative schlieren systems [PDF]

open access: yesINCAS Bulletin
The present paper details the recent advances in three schlieren visualization methods, considering only those applied to obtain values of gas-dynamic parameters of the phenomenon, namely SIV (schlieren image velocimetry), CCS (color-calibrated schlieren)
