Turbulence and transition modelling for compressible fluid dynamics


Research objectives and content
a) Implementation and evaluation of recent developed turbulence models. The models considered include both algebraic and differential methods with extensions towards compressibility. b) Modifications and/or extensions of existing turbulence models to perform better for external aerodynamics. The emphasis will be on the use of the edge intermittency, evaluated either by an algebraic model or by a recently developed differential model. c) Implementation and evaluation of transition models, conceived and studied for internal flows, will be applied to external flows. The different models will be based on the use of a transitional intermittency factor, either determined algebraically or by the use of a differential model. Training content (objective, benefit and expected impact)
Objective: to get familiar with the difficulties and the applied techniques for external aerodynamics with or without compressibility effects. Special attention will be given to turbulent and transitional phenomena.
Benefit: understanding the deficiencies of the different models used in external (compressible) aerodynamics and gaining insight in the underlying physics of turbulence and transition.
Expected impact: the acquired expertise might result in models that are more generally applicable both for internal and external aerodynamics. Links with industry / industrial relevance (22)
The different research objectives are of particular interest to the aeronautical industry (e.g. DASA, Dassault....) which collaborate strongly with the host institution.
