Learning Objectives:
Students will become familiar with the operation of various turbulence models implemented in common flow simulation programs. They will gain the ability to evaluate various types of turbulence models, each with significantly different behaviors, concerning accuracy, stability, and computational demands. Additionally, the derivation of selected models will be covered. This knowledge enables the meaningful application of CFD (Computational Fluid Dynamics) to technical flows encountered in industrial practice.
Course Contents:
Review of basic fluid mechanics and numerical fundamentals, an overview of turbulence theory, introduction to Direct and Large-Eddy Simulation. Detailed treatment of statistical turbulence models (eddy viscosity and Reynolds stress models). Hybrid models: Scale-Adaptive (SAS), Detached-Eddy (DES). Boundary layer treatment, laminar-turbulent transition, modifications for stagnation, rotation, and compressibility.
Structure:
The lecture is complemented by practical computer exercises. To begin, an introduction to flow simulation with OpenFOAM is provided, followed by closer examination of examples from the lecture.
Materials:
Course materials include lecture slides and exercise materials. Various references are provided during the lecture.
Prerequisites:
Fundamentals of fluid mechanics, ideally also Advanced Fluid Mechanics, Computer Simulation of Fluid Flows.
