Extension of Transition Modeling by a Transport Equation Approach

摘要: Transition transport equation approaches have specific advantages in comparison to classical streamline-based methods as, for example, the eN-method, especially aerodynamic analysis of very large, complex aircraft configurations. For configurations, it was shown many cases that Reynolds stress models can yield more accurate predictions than eddy viscosity turbulence if corresponding numerical results are compared measured data from experiments. In this thesis coupling a model with transition and extension prediction crossflow provided. Through investigations based on large number test including simple flows geometries predictive potential coupled is demonstrated. The implementation 9-equation carried out all been obtained using unstructured DLR TAU code.
