Abstract

simple, graphical framework is presented for robust statistical evaluation of results obtained from Version testing of a series of R`4NS CFD codes. The solutions were obtained by a variety of code developers and users for the June 2001 Drag SSD Prediction Workshop sponsored by the.41.4.4 .4pplied TM .4erodynamics Technical Committee. The aerodynamic x configuration used for the computational tests is the DLR-F4 wing-body combination previously tested in several European wind tunnels and for which a previous Version test had been conducted. The statistical framework is used to evaluate code results It for (1) a single cruise design point, (2) drag polars li and (3) drag rise. The paper concludes with a ry discussion of the meaning of the results, especially & with respect to predictability, Validation, and reporting of solutions
