Abstract

In order to analyze spray combustion mechanism, it seems to be important to reveal behaviour of fuel spray in flame. Particle size measurement by in-line Fraunhofer holography is widely applied. But few reports have been presented which discuss measurement of particles in flame due to difficulty caused by rapid refractive index variation. In this article, experimental evaluation has been made for measurement accuracy of in-line Fraunhofer holography. And quantitative evaluation has been performed by measurement of spatial intensity distribution in real-image plane. Then holographic interferometry and in-line holography are applied to freeze fuel particle in flame.
