This visualization, from a collaboration between #NASA and #Boeing about airframe noise prediction, shows the simulated air flow field around the nose landing gear of a Boeing 777, representing the complex unsteady flow generated by the gear components. The visualization is q-criterion colored by speed, from slower green to faster red air velocities. A strong vortex appears coming off the edge of the landing gear doors. Simulations run on NASA supercomputers at Ames allow researchers to better understand the changes in flow behavior that contribute to airframe noise.
