RANS Simulations with One and Six Degrees of Freedom Rigid Body Motions

  • Thorsten Schwarz
Part of the Notes on Numerical Fluid Mechanics and Multidisciplinary Design (NNFM) book series (NNFM, volume 96)


A one rotational degree of freedom and a six degree of freedom flight mechanics module are coupled to DLR’s RANS solver FLOWer. The algorithms used to solve the equations of motion are described. The 1-DOF module is validated for a freely rolling delta wing. A very good agreement with experimental data is observed. The capability of the 6-DOF module is demonstrated by a simulation of a store separating from a wing. The computation uses the overset grid technique to handle the movement of the bodies in relative motion.
