ECTS: 4

Description:

Computational Fluid Dynamics (CFD) has been successfully used in innovative design, trouble-shooting, optimization of technologies and facilities in numerous areas. This advanced CFD course will provide a familiarity with and an in-depth understanding of the following topics and issues:

Day 1: Fundamentals of CFD

Intro to CFD; the finite volume method for various steady and unsteady problems; different spatial and temporal discretization schemes, their formulation, assessment and applicability. Lecturer: Chungen Yin; 7.4 hours

Day 2: RANS turbulence modeling

SIMPLE algorithm for pressure-velocity coupling; fundamentals of turbulence; different isotropic eddy viscosity models; near-wall modeling; meshing impact and strategies. Lecturer: Chungen Yin; 7.4 hours

Day 3: Multiphase flow modeling

Different methods for multiphase flow modeling such as Lagrangian method, Eulerian method, mixture & volume of fluid approach; modeling multiphase flow in porous media. Lecturer: Torsten Berning; 7.4 hours

Day 4: Turbulent combustion modeling and user-defined functions

Combustion analysis tools; species transport/eddy dissipation or EDC; mixture fraction/PDF; fundamentals & examples of user-defined functions. Lecturer: Chungen Yin; 7.4 hours

During each of the four days, lectures will be combined with demos and hands-on sessions, in order to achieve the above objectives.

Prerequisites:

Basic knowledge in fluid flow, turbulence, multiphase, combustion, programming

Form of evaluation:

Finish one of the following tasks and the corresponding mini-project report.

1. numerically solve a general transport equation using the finite volume method and the key results; or
2. modeling of a turbulent flow using a commercial CFD code both by the default software and by developing and integrating user-defined functions.
