LES at Work: Quality Management in Practical LES

Paper i proceeding, 2008

This paper aims at reviewing some important aspects of Large Eddy Simulation (LES) as applied to engineering applications. In particular we focus on aspects relevant to quality management and validation and verification procedures. After outlining the LES formalism and the numerical methods considered appropriate for engineering applications we discuss particular features of LES that require specific treatment or attention in the validation and verification process. This is illustrated in more detail when different flows are introduced and discussed. Applications are selected from different fields, and are of different complexity, being supported by reference data, to demonstrate a variety of modeling aspects in engineering. Finally, we connect the various aspects of validation and verification with the technical aspects of engineering LES.
