This course focuses on the momentum and energy transport. The `momentum and energy transport' starts with the comparison of these transports with the mass transport so as to understand the analogy of these three transports in terms of the relation between flux and driving force. With respect to the momentum transport, Newton's law of viscosity and Navier-Stokes equation are explained and applied to the calculation of the velocity profile of fluid and the shear stress acted on the wall assuming that the fluid is laminar. Dimensionless factors such as Reynold's number and friction factors are also introduced. Viscosity will be related with the structure of materials. With respect to the thermal conduction, Fourier's law of heat conduction is applied to the calculation of temperature distribution in solid materials. As for the radiation heat transfer, absorption and emission at solid surfaces are explained so as to introduce the calculation method of radiant energy transfer between two bodies at different temperatures. The studies in this course will give you the important concepts on the research and development of high temperature materials and processes.
By the end of this course, students will be able to:
1) Understand the analogies between mass, momentum and energy transports.
2) Calculate the velocity distribution of laminar and steady-state fluids using Navier-Stokes equation.
3) Calculate the temperature distribution in solid materials using Fourier's law of heat conduction.
4) Calculate the radiant energy transfer between two bodies at different temperatures.

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.
