FLUID DYNAMICS ASSOCIATED TO LAUNCHER DEVELOPERS
(STO-AVT-206-VKI)
From April 15-17, 2013
von Karman Institute, Rhode-St-Genèse, Belgium
Computational Fluid Dynamics play more and more a key role in the design and qualification of future launcher developments. CFD is not only used for improved understanding of fluid physics in ground based facilities but also to establish the required data base for design in flight conditions. Fundamental is the validation of the modeling associated with critical phenomena and their remaining uncertainties driving the margins for design.
The course will be a top down, industrial driven course addressing key elements for future launcher developments and will be given by key experts in the field.
The course will provide an overview of the key fluid dynamic issues driving the design of launchers and will elaborate in detail on topics such as: propulsion systems with emphasis on start up and shut down, propellant behavior, combustion instability, sloshing phenomenon, phase change events, cavitation, cryogenic and two-phase flows, pressure oscillations and slag accumulation in solid rocket boosters, nozzle optimization and flow detachment, side loads as well as address overall propulsion system simulation tools such as the ESPSS ( European Space Propulsion System Simulation).
In addition special sessions will be devoted to external aerodynamics and aerothermodynamic elaborating on aeroacoustics at take off and unsteady aerodynamics in flight such as buffeting, nozzle coupling, thruster jet interaction and staging. The course will provide a forum for discussion on real applied design issues describing the underlying physics thereby improving the general knowledge base for future launcher developments.
The Lecture Series directors are Jean Muylaert, Director of the von Karman Institute and Serge Radulovic from Astrium EADS.
