개요

The WKWY-300 color schlieren can be used to observe the distribution, propagation process, and intensity of disturbances caused by various factors in transparent media. Scientific research on changes in flow field density in disciplines such as laser matter interaction, laminar flow, multiphase flow, heat and mass transfer, shock waves, supersonic flow, combustion, flames, explosions, plasmas, internal ballistics, and certain chemical reactions.

제품 정보

WKWY-300Color shadowgraphIt is based on the principle that the refractive index gradient of light in the measured flow field is proportional to the airflow density of the flow field. The change in density gradient in the flow field is transformed into the change in relative light intensity on the recording plane, which makes the density changes of shock waves, compression waves, etc. in the compressible flow field drastic. This can be used to observe the distribution, propagation process, and intensity of disturbances caused by various factors in transparent media. Scientific research on changes in flow field density in disciplines such as laser matter interaction, laminar flow, multiphase flow, heat and mass transfer, shock waves, supersonic flow, combustion, flames, explosions, plasmas, internal ballistics, and certain chemical reactions.

Scientific research on changes in flow field density in disciplines such as laser matter interaction, laminar flow, multiphase flow, heat and mass transfer, shock waves, supersonic flow, combustion, flames, explosions, plasmas, internal ballistics, and certain chemical reactions. The Tipler schlieren is a traditional and widely used type.

WKWY-300Color shadowgraphThe main optical components of the system can be divided into three parts: the light source slit system, the main spherical reflector adjustment mechanism, and the knife edge imaging system. Among them, the light source slit system and one of the main spherical mirrors form a collimation system, and the knife edge imaging system and one of the main spherical mirrors form a schlieren viewing system, which are respectively arranged on two platforms.
