Abstract
The Background Oriented Schlieren (BOS) technique13; has been applied to obtain the density field of a13; complex underexpanded jet flow. The measurements13; were made on an axisymmetric converging nozzle13; (Mj=1) operating at moderately and highly expanded13; values of nozzle pressure ratios. The validation of the13; Filtered Back Projection Tomography (FBPT) used13; in this technique was done by extracting the central13; plane of a 4-jet configuration. Density fields for two13; nozzle expansion ratios are presented. The study13; shows that meaningful quantitative data can be13; extracted using minimal hardware with this13; technology.13;
