This course focuses on the fundamentals of numerical analysis of thermo-fluid dynamics. Firstly the governing equations of thermo-fluid dynamics, which express the conservation of mass, momentum, and energy, are presented. Secondly the discretization of governing equations, numerical solving method of discretized equations, and the numerical errors in numerical analysis are explained. Finally the numerical simulation on the simple steady flow is conducted as an exercise.
Computational fluid dynamics (CFD) is widely used for designing the energy conversion systems such as internal combustion engines, turbo-charger. We need to understand the principles of numerical simulation of thermo-fluid dynamics and apply the numerical analysis to the actual systems for the validation of the computed results by CFD and developing the new models of thermo-fluid phenomena. In this course, the processes of numerical analysis of heat transfer and fluid flow are explained with examples of analysis in the simple field. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of numerical analysis of thermo-fluid dynamics widely applicable to analysis of energy conversion systems.
By the end of this course, students will be able to:
1) Explain the physical meaning of governing equations of heat transfer and fluid flow.
2) Discrete the governing equations.
3) Explain the source of error in the numerical analysis.
4) Explain the methods for solving the discretized governing equations.

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
At the beginning of each class, solutions to exercise problems that were assigned during the previous class are reviewed. Towards the end of class, students are given exercise problems related to the lecture given that day to solve. To prepare for class, students should read the course schedule section and check what topics will be covered. Required learning should be completed outside of the classroom for preparation and review purposes.
