Abstract

 To study the flow characteristics of a two-dimensional jet in crossflow, a slit jet of 1 mm width has been used. The concentration distribution was obtained experimentally using image digitizing technique. The velocity distribution was theoretically studied using a two-dimensional model. A jet centerline trajectory was traced based on both maximum concentration values and maximum velocity values along the flow field for the experimental and theoretical cases, respectively. A reasonable agreement was indicated between both traces. This result can be extended for studying the three dimensional jets in crossflow. An experimental correlation has been developed for jets ist crossflow at different velocity ratios for both near- and far-field.
