Abstract
Struetural features resulting from the interaction of a turbulent jet issuing transversely into a uniform stream are deseribed with the help of flow visualization. Jets to erossflow velocity ratios have been investigated with primary goal of introducing a new experimental technique to study characteristics of jets in crossflow. The technique introduced in this study called image digitizing technique. It is based on capturing series of images using a high speed digital camera then processing the obtained images. Accordingly, a new definition for the average image has been introduced and applied. The obtained conclusions are; Image digitizing technique, provided and used in this study, is a reliable and inexpensive technique. The new method of averaging is more deseriptive for jet characteristics. Jet characteristics, e.g. eonccntration distribution, jet centerline, jet boundaries, .. CIH, can be studied using image digitizing technique. Roll-up shear layer vortiees are obtained, which can help in explaining their role in the entrainment mechanism.
