Trajectory and Mixing Scaling Laws for Confined and Unconfined Transverse Jets
Abstract
Transverse jets play an important role in many propulsion-related applications including gas turbine burner dilution, exhaust from V/STOL aircraft, and fluidic thrust vectoring. Although this flow has received extensive research attention over several decades, a lack of universality exists regarding scaling laws available in literature. Using data from existing literature, a foundational scaling law framework has been proposed for the jet trajectory and mixture uniformity. A newly derived parameter demonstrates an improved collapse of trajectory data in literature. This parameter was derived using theoretical arguments that both entrainment and aerodynamic drag should be considered as relevant mechanisms of momentum transport between the jet and cross flow. Future work will extend this scaling law framework towards the extreme conditions associated with rocket engine preburners.
