Course description and aims

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.

Student learning outcomes

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.

Keywords

Incompressible flow, compressible flow, numerical analysis, discretization scheme, finite difference method, finite volume method, computer simulation, programming

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

We start with the governing equations of fluid mechanics, and then study discretization methods, discrete equations, typical solution methods of incompressible flows, and numerical methods for compressible flows which include TVD schemes and Riemann solvers. In addition, new developments in the field of computational fluid dynamics, such as multiphase flow simulation and high-performance computing will be also introduced.

Out-of-Class Study Time (Preparation and Review)

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.
