Part of the Notes on Numerical Fluid Mechanics and Multidisciplinary Design (NNFM) book series (NNFM, volume 89)

Summary

This paper comprises the developments of the block structured Navier-Stokes solver FLOWer during the DLR project MEGAFLOW II. At first the status of the FLOWer code including its numerical and physical capabilities at the end of MEGAFLOW II is presented. After introducing the objectives of the FLOWer development for MEGAFLOW II the major developments and corresponding results are discussed.
