Turbulence Modeling for 3D Wall-Bounded Flows - a Literature Survey -

Kurzfassung

A literature survey has been conducted on the performance of existing turbulence models when applied to wall-bounded flows with a three-dimensional (3D) mean velocity field. The flows considered are external boundary layers, flows near a junction between two walls, and various internal flows. The objective is to provide advice on the choice of a turbulence model, and to offer a general introduction to these flows from a modeling point of view. The report is organized as follows: the first chapter consists of a general introduction including some basic concepts and a discussion of the different ways a boundary layer becomes three-dimensional. The formation mechanism also characterizes to a large extent the way the 3D flow evolves, and is therefore used to classify the flows considered. The next chapter contains a general discussion of applying existing models to 3D flows and a listing of some models. In each of the following chapters, a group of 3D flows, as classified in Chapter 1, is discussed. These chapters contain the following parts.
