Abstract

The presentation focuses on the CFD analysis done in support of NASA's Juncture Flow Experiment (under NASA’s Transformational Tools and Technologies Project (T3). The first phase of the Juncture Flow experiment, performed in NASA Langley’s 14- by 22-Foot Subsonic Tunnel, has been completed. Comparisons between OVERFLOW CFD simulations and wind tunnel experimental results will be shown. Oil flow results, surface pressure cuts, velocity profiles, and Reynolds stress profiles will be compared. Preliminary results analyzing the effect of grid resolution, wind tunnel walls, and turbulence models on the Juncture flow region will be presented. The results are not meant to be a validation study, but more as a preliminary evaluation of the current status of Reynolds averaged Navier-Stokes (RANS) CFD simulations.

Biography

Henry Lee is an aerospace engineer with Science and Technology Corporation, working with both the SLS group at NASA Ames Research Center and the Juncture Flow experiment design committee in the Computational Aerosciences Branch of the NASA Advanced Supercomputing Division. He obtained his Bachelors from University of California, San Diego in 2007, and his Masters in Aeronautics/Astronautics Engineering from Stanford University in 2009.

Seminar Participation

Attending In Person

For select seminars, you may wish to attend in-person if you are in the vicinity of NASA Ames Research Center. These AMS seminars are held in Building N258 in Room 127, just off the front lobby. Sessions available to attend in-person will be indicated in the announcement information. In-person participants without NASA badges will need a valid visitor badge (US citizenship or permanent residency is required) to enter the facility.
