The experimental method using schlieren apparatus.Schlieren method of this kind of way to point will be discussed with the help of a diagram.A light source, a lens (called the schlieren lens in the future), and as the light source.As usual mapping table clear according to obtain the infinite light cone.Today it is important to pay attention to in main lens three-dimensional point where sources of each beam of light on the light.Two beams of from the end of the lens to the Angle O.On (&) and (c) draw a bunch of this type of beam to clarify.See from figure pulled out a small Angle of the prism.Before pull out a prism, the light surrounded within the two dashed lines.After pull out a prism, the twists and turns up to the light, solid line status.Because is to pull out a prism, make from x and through the process on the three-dimensional straight blade increased the amount of light.These increases the amount of light are included in the do in the Angle of the beam.On the object lens, generated by the point like a three-dimensional, response to increase the intensity of illumination.Was clarified the uniformity of the brightness of the light source, and so much clearly sure because so much as on line is very clear and in parallel and straight blade.Straight blade is like line spacing for o.Once assumed schlieren assembly plans to make w Angle is small, and even in x as the intensity of illumination/stereo with.Direct proportion, and the intensity of illumination define as stereo on unit area of light energy.Beam deflection zko Angle to make.Our company's main equipment and technology has the schlieren apparatus, photonic doppler velocimeter, planar laser induced fluorescence PLIF, etc.If there is any need to please contact us: 0816-6204826
