Diffraction Profile

We developed a Small Particle Sizing Algorithm (SPSA) that utilizes Fresnel and Fraunhofer diffraction profiles to determine sizes of small spherical particles from 1 to 10 μm in diameter. The SPSA uses standard shadowgraphy techniques to generate an image of the diffraction profile from which two characteristic parameters are measured, image size and image slope. Over specified ranges, the combinations of these parameters are unique, enabling the simultaneous calculation of particle size and distance from the object plane of the CCD camera.

Spray Penetration

Light scattering based particle sizing techniques have the advantage of nonintrusively measuring sizes of emulsions and dispersions. Depending on the parameters involved, there are several techniques that can be used and a choice of the most convenient method can be made. When the particles are large, Fraunhofer Diffraction Pattern Analysis (FDPA) can be employed in measuring particle-sizing distributions. The design of a high quality diesel engine would involve an understanding of the disintegration mechanism, spray penetration, and spray motion. It is the objective of this paper to implement the FDPA laser diffraction method to determine spray penetration and droplet mean diameters, for single injection of diesel fuel with synchronized time that will allow time dependent studies.
