WebSchlieren (plural for the German word “schliere”) are optical inhomogeneities in transparent materials. In supersonic flow, air experiences very large changes in density as it approaches, passes through and trails shock waves. As the density … This video demonstrates a single-pass high-speed schlieren system capturing the transitional ballistic sequence of a handgun. Colored schlieren image of the thermal plume from a burning candle, disturbed by a breeze from the right Schlieren(/ˈʃlɪərən/SHLEER-ən; German: [ˈʃliːʁən], lit. See more Schlieren are optical inhomogeneities in transparent media that are not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of such inhomogeneities. … See more Schlieren flow visualization is based on the deflection of light by a refractive index gradient The index gradient is directly related to flow density gradient. The deflected light is … See more • Background-oriented schlieren technique • Laser schlieren deflectometry • Mach–Zehnder interferometer See more Schlieren were first observed by Robert Hooke in 1665 using a large concave lens and two candles. One candle served as a light source. The warm air rising from the second candle … See more The schlieren effect is often used in video projector technologies. The basic idea is some device, such as a liquid crystal light valve, is used to produce schlieren distortions in a controlled manner and these are projected on a screen to produce the desired image. … See more • Background oriented schlieren for flow visualisation in hypersonic impulse facilities • Visualisation of supersonic flows in shock tunnels using Background Oriented Schlieren (BOS) technique • Video on Schlieren photographs See more WebApr 11, 2024 · This paper investigated two types of jet interaction under different pre-chamber structures, including the jet-crossing and unequal nozzle designs.
