授業目標

In order to design and control machines related to thermal energy, it is necessary to analyze and understand the flows of thermal fluids inside/outside the machines. Thus, this course focuses on the methods of numerically analyzing thermal fluid flows, particularly in turbulent flow regimes. The detailed theories, practices and their backgrounds are lectured.
The goal of the students is to understand the fundamental theory and tactics of turbulence modeling.

成績評価

The final test is for evaluating the level of the student's learning achievement.
Evaluation of the levels is made by the Final Test (70%)
and Assignments (30%).
By the total scores obtained, the final letter grades will be assigned as follows:
A+= 90-100 %
A= 80-89 %
B = 70-79 %
C= 60-69 %
D = 59 % and below (fails to obtain the credits)
