Schlieren apparatus flame photography.In smoke-free erupted or the rest of the dyed material such as sodium fire, the bright region is put out the chemical reaction zone of the wave.Indirect pictures out wave technology, in addition to flame photometric may not satisfied with very short exposure time request, the haven't come up with some points.This deal with hydrogen flame is accurate, because this kind of flame in addition to the high level and pressure of the detonation wave, from the perspective of the scale of visible light is too dim.Mixture of carbon monoxide, oxygen flame than hydrocarbon - oxygen flame somewhat weak, but for indirect pictures, the light intensity is enough as usual.Indirect flame photograph taken many of the examples have been reproduced in this book.Under the light bright lighting, air flow can be seen by floating dust particles.When using stroboscopic light, particle trajectory in the photograph so presented in a straight line, the length of the distance is the caliber of particle velocity.A few pieces of this kind of photos are reproduced in this book.The company (sichuan branch optical precision machinery co., LTD.) the main production: schlieren apparatus, photonic doppler velocimeter, PLIF planar laser induced fluorescence, and other equipment.If there is need to please contact us: grain shadow instrument 0816-6204826
