Abstract
Flow visualization has long been employed in experimental study of fluid mechanics and heat transfer phenomena. Two widely used methods are those utilizing scattered light from small particles, and those utilizing the variation in refractive index, commonly known as schlieren (density gradient) and shadowgraph (second derivative of density gradient). LSM (light scattering method) generally requires foreign materials to be seeded in the flow and RIM (refractive index method) is applicable only when noticeable variations in density are observed. Detailed reviews of these methods can be found in Merzkirch. The purpose of this paper is to describe the 2-D LSM for the visualization of jet flames, and to compare images obtained from LSM and RIM techniques.
