PAB3D Simulations for the CAWAPI F-16XL

USM3D Unstructured Grid Solutions for CAWAPI at NASA LaRC

“…In general, the USM3D predictions agree better with measured data than those from CFL3D:BL-DS 4 , but both solutions only fairly approximate the measurements. Similar trends are noted by others in the CAWAPI facet [7][8][9][10][11][12][13][14][15] of the AVT-113 task group. Moreover, from Fig.…”

“…rake positions were chosen 4 so that #3 would be in basic free-stream flow, #4 underneath the primary vortex, #5 underneath the secondary vortex, and #7 on the secondary vortex separation line. Regarding the USM3D and PAB3D 7 solutions, both predict the entire profiles well for all four B.L. rakes, though USM3D is slightly better for rakes #3 and #7.…”

“…For example, it is known 6 that grid adaptation in the flow-field can be very important for votical flows, yet even the baseline grid -developed for a vortical flow FC -made no provision for such adaptation. Lastly, the paper provides a description of the solver; and comparisons with previous CFD solutions 4 and those of PAB3D 7 , a structured grid flow solver at LaRC, for surface pressures, boundary-layer profiles and skin-friction distribution.…”

A Survey of Factors Affecting Blunt-Leading-Edge Separation for Swept and Semi-Slender Wings

“…CFD solutions were contributed from nine groups using ten different solvers, including both structured and unstructured approaches, to assess predictive capabilities for these data. Two special sessions at the 45 th AIAA Aerospace Sciences meeting highlighted these individual contributions [references [47][48][49][50][51][52][53][54][55][56][57], and a summary paper by Rizzi 57 [2007] was also included. Considerable effort went toward modeling the complex aircraft geometry at the high Reynolds numbers of the flight test data.…”

Overview of the Cranked-Arrow Wing Aerodynamics Project International

“…Both of these can lead to significant time reductions from geometry specification to solver results. In the listing of papers that follow, authors have utilized their solvers American Institute of Aeronautics and Astronautics -structured [19][20][21] or unstructured [22][23][24][25][26][27][28] -in order to determine the best practices for each code and type of flow combination and then made comparisons with each other's predictions or flight data as they deemed appropriate.…”
