Effect of jet inclination angle and hole exit shape on vortical flow structures in low-reynolds number jet in cross-flow (2012)
Journal Article
Yao, Y., Maidi, M., & Yao, J. (2012). Effect of jet inclination angle and hole exit shape on vortical flow structures in low-reynolds number jet in cross-flow. Modelling and Simulation in Engineering, 2012, 1-7. https://doi.org/10.1155/2012/632040

Numerical studies have been performed to visualize vortical flow structures emerged from jet cross-flow interactions. A single square jet issuing perpendicularly into a cross-flow was simulated first, followed by two additional scenarios, that is, in...
