The primary objective of this web site is to provide code validation data for the PAB3D community. Following the example of the Wind validation site, analytical, computational, and experimental data are provided to support independent assessment of the software's capabilities and foster comparisons with other codes. The objective is to assess accuracy, provide confidence, and evaluate performance.

The validation effort is an on-going activity and PAB3D users and the CFD community at large are encouraged to propose candidate validation problems, and to submit documentation and results from independent validation efforts for possible inclusion in the archive.
 

This case involves a "submerged" turbulent supersonic jet emanating from an axisymmetric convergent-divergent Mach 2.2 nozzle. This nozzle was studied by J.M. Eggers in 1962. Velocity profiles and eddy viscosity distributions were obtained within the jet. The working fluid is air and the nozzle is operated at the pressure ratio corresponding to perfect expansion.  This case uses the grid and experimental data included in the NPARC code validation archive and the Wind validation archive.
