Rainbow Refractometry

Abstract Both experimental and computational work are important in the study of spray evaporation and combustion; therefore, it is essential that a link between the two areas be established. In this study, measurements of a full cone spray using phase-Doppler interferometry and Rainbow Refractometry are presented and compared with computational results. The computation results were acquired using a KIVA-3V code, which is specifically designed to analyze transient, two- and three-dimensional, chemically reactive fluid flows with sprays. Specifically, in this study, the droplet size, velocity and temperature distributions were measured at various locations within the full cone spray. Using the same initial and boundary conditions, computation results were obtained at corresponding locations and compared with the experimental results. The experimental and computational results agree very well and indicate similar droplet size, velocity and temperature distributions at the corresponding locations. Additionally, the cooling rates and movement of the droplets show the same trends.
