- Experiments on flow about simple bodies dropped in water tanks and shear layers in a water tunnel, were performed to study the application of the schlieren technique to water flow. It is verified that small residual temperature differences initially present in the fluid, lead to substantial temperature gradients near the surface of the models. The resulting gradients in index of …

- Schlieren Photography. Schlieren photography (from the German word for "streaks") allows the visualization of density changes, and therefore shock waves, in fluid flow. Schlieren techniques have been used for decades in laboratory wind tunnels to visualize supersonic flow about model aircraft, but not full scale aircraft until recently. Dr. Leonard …

- Schlieren photography is similar to the shadowgraph technique and relies on the the fact that light rays are bent whenever they encounter changes in density of a fluid. Schlieren systems are used to visualize the flow away from the surface of an object. The schlieren system shown in this figure uses two concave mirrors on either side of the test section of the wind …

- Schlieren photography is an optical technology that can photograph the flow of fluids of varying densities, which is used to record regions of different refractive index in a fluid, and is especially used to visualize the flow of air around objects. Schlieren flow visualization is based on the deflection of light by the flow density gradient, so gases in the workplace with different …

- Step 1: Materials. Here's what you'll need to create a Schlieren system of your very own: Parabolic/spherical telescope mirror with long focal length. Camera. Telephoto lens. Razor blade. Point light source. Parabolic/Spherical Mirror - For this project, a bigger mirror, and a longer focal length, are both desirable.
