Lateral jet injection into swirling combustor flowfields

Abstract

An experimental program has been conducted to ascertain the effects of the number of lateral jets, the jet velocity ratio, and the crossflow swirl strength, on the isothermal flowfield patterns in jets injected normally to a round-section crossflow. Attention has been given to the trajectory, penetration, and mixing efficiency of the lateral injection, using flow visualization, pitot-probe and hot-wire methods. In addition, such predictive techniques as a simple, explicit, fully three-dimensional turbulent computer code have been employed.
