キーワード Keywords:

computational fluid dynamics, incompressible flow, finite volume method, turbulence modeling, eddy viscosity, k-e, large-eddy simulation



授業の目標 Objectives:

To make students understand the numerical methods of solving the governing equations for incompressible flow and to give a working knowledge of how to validate the numerical method adopted. Special emphasis is on the treatment of turbulence, in which development of turbulence models is discussed. Finally some examples of the application of turbulence simulation to engineering problems are introduced.



到達目標 Goals:

Students completing this class should be able to obtain the best solutions to a specific flow problem he is facing from a commercial CFD software, by adopting a proper numerical scheme, applying appropriate boundary conditions, developing high-quality calculation grids, and using a suitable turbulence model



授業計画 Outline:

1.Numerical methods in incompressible flow simulation (5)

- Finite volume method for flow equations

- Velocity-pressure coupling algorithm

- Numerical accuracy and errors

2. Validation and qualification (2)

- Quality of calculation grid

- Design of boundary and initial conditions

- Examples of validation and quality tests

3. Introduction to turbulence simulation (2)

- Averaging or filtering

- Equations for the averaged field and the closure problem

- Eddy viscosity concept

- Classification of turbulence simulation

4. Turbulence modeling (5)

- Eddy-viscosity models

- Reynolds-stress models

- Large-eddy simulation

5. Application to engineering problems (1)


成績評価の基準と方法 Grading:

The grading is based on the homework to be assigned at the end of every class. Those who attend less than 60% of the classes will fail the course. S=90-100, B=80-89, C=60-79, D=59 or less.



テキスト・教科書 Textbooks:

Not compulsory but following two are helpful: Computational methods for fluid dynamics (Ferziger and Perić) and A first course in turbulence (Tennekis and Lumley)
