Abstract
During the ascent of carrier rockets the massively separated flow in the base region generates highly unsteady wall pressure fluctuations. The resulting dynamic loads can induce a response of the launcher structure called buffeting. In order to study the characteristics of the base flow behind three different configurations of the Ariane~5 launcher, Improved Delayed Detached Eddy Simulation (IDDES) in combination with unstructured grids is used. The objective of this work is to demonstrate the ability of IDDES to describe the impact of the connecting struts between central stage and boosters and to analyze the efficiency of a buffeting reduction device in the base region. Comparisons of the numerical results with time resolved and time averaged surface pressure data and PIV measurements obtained from the DNW High Speed Wind Tunnel are carried out in good agreement.
