| Abstract | Direct numerical simulations are used to study a round turbulent jet in a laminar crossflow. The velocity ratio is 5.7 and the Reynolds number is 5000. Mean velocity and turbulent intensity profiles available from experiment (Su & Mungal 2004) are compared to simulation results, and good agreement is observed. A two-dimensional model problem is used to study the evolution of the jet cross-section and the counter-rotating vortex pair (CVP). The model problem shows how the trailing edge of the jet deforms and yields a CVP at later times. The initial stages of the evolution are at constant acceleration; i.e. pressure-driven while the later stages are at constant velocity; i.e. momentum driven. The model problem is used to suggest a pressure-based argument for CVP formation. |
