Simple usage of schlieren apparatus referred to as "schlieren method, schlieren apparatus is the basic requirement of the schlieren method, if there is no schlieren apparatus, you need to other instruments.Schlieren method adds a "blade".Let through the experimental section of the project the light at the edge of image, through another lens and projected onto the screen, due to dense areaFor the large deflection is blocked by the blade, appear on the screen dark grain, small area density because of small deflection is not blocking, present bright lines on the screen.Made by the inhomogeneity of densityInto the screen brightness uneven schlieren, measuring the scale of the schlieren can calculate the discount partial light.The law has the structure briefly, the advantages of high sensitivity, in aerodynamics,Thermodynamics is widely used in the experiment.Over the years has developed the interference pattern, quantitative grain shadow, shadow testers, colorful lines shadow device such as a variety of schlieren apparatus.Our company is a professional schlieren apparatus equipment production company, main products are: schlieren apparatus, photonic doppler velocimeter, PLIF planar laser induced fluorescence, and other equipment, if there is need to print a shadow instrument, just contact us: 0816-6204826 |
