Schlieren photography — is a visual process that is used to photograph the flow of fluids of varying density. Invented by the German physicist August Toepler in 1864 to study supersonic motion, it is widely used in aeronautical engineering to photograph the flow of air… … Wikipedia
schlieren photography — /ʃlɪərən fəˈtɒgrəfi/ (say shlearruhn fuh togruhfee) noun a method of photographing flow patterns in a turbulent, transparent fluid which depends on differences in density and refractive index within the fluid. –schlieren photograph, noun …
Synthetic schlieren — is a process that is used to visualize the flow of a fluid of variable refractive index. Named after the schlieren method of visualization, it consists of a digital camera or video camera pointing at the flow in question, with an illuminated… … Wikipedia
