Abstract

This presentation shows a summary of an ongoing numerical investigation underway at the DLR Goettingen, dealing with the influence of various modelling parameters on numerical simulation of unsteady transonic flows. The focus of research lies on a simulation of self-sustained shock oscillation (shock-buffet) since this mechanism can play an important role in the aerodynamic and aeroelastic behaviour of modern large-span aircrafts. In the investigation the DLR Tau code, a time-accurate RANS flow solver based on the finite-volume approach, is used. It employs an unstructured spatial flow field discretisation and dual-time stepping scheme for time-accurate (unsteady) calculations. Presented is an analysis of the results obtained with URANS simulation and Spalart-Allmaras-based Detached-Eddy Simulation (DES) of shock-buffet phenomena occuring on a supercritical NLR 7301 aerofoil.
