Computational fluid dynamics is an essential and advanced tool to solve fluid mechanic problems in scientific and engineering researches. In this course, you will learn the numerical methods and stills to solve the governing equations of fluid mechanics, based on the basic knowledge of fluid mechanics and numerical analysis you have acquired in the undergraduate studies.
The lectures will cover the fundamental numerical approaches to solve compressible and incompressible flows, as well as well other advanced topics. Students are expected to learn not only the knowledge about the numerical methods but also skills to develop computer codes through practice.

We start with the governing equations of fluid mechanics, and then study discretization methods, discrete equations, typical solution methods for compressible and incompressible flows. In addition, turbulence modeling with applications and new developments in the field of computational fluid dynamics, such as high-performance computing and large-scale simulation will be introduced as well.

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Learning achievement is evaluated by reports and excercises. Programing practice may be required in some cases.
It is desirable to have the knowledge on fundamentals of thermo-fluid dynamics and numerical analysis
