MAEN4300 Fluid dynamics and computational methods Course description

The course will provide some basic knowledge of fluid mechanics and mass transfer, as well as good skills in calculating fluid dynamics problems linked with heat and mass transfer. Numerical methods (computers) must be used to solve realistic problems. The course provides a brief introduction to general computational methods for the natural sciences and particularly focuses on the numerical solutions of coupled heat and fluid dynamics problems including mass transport.

All aids permitted.

• performing service life predictions for concrete structures in marine environments.
• performing calculations of greenhouse gas emissions for concrete structures.
• proposing measures to extend the service life of concrete structure.
• performing capacity assessments of a damaged concrete structure or component.

General competence:

The student is capable of;

• understanding and analyzing scientific publications on topics related to sustainability and durability of concrete structures.
• applying theories in practice based on scientifically justified choices of relevant sustainable solutions.
• presenting academic results and evaluations in a scholarly manner

The teaching consists of lectures and exercises. The students will also be given a major project assignment, in groups of 2-3 students. The project assignment shall be presented in the form of a scholarly report.

A handheld calculator that cannot be used for wireless communication. If the calculator's internal memory can store data, the memory must be deleted before the exam. Random checks may be made.

Graded scale A-F.

The assessment (exam) is a project assignment (portfolio) consisting of two assessment parts:

1) Project report, prepared in groups of 2-3 students, approx. 40-50 pages (excl. appendices).

2) Oral exam, in group, based on the project.

The assessment cannot be appealed.

The exam will be assessed together as a portfolio with one grade at the end of the semester, but all the parts that make up the portfolio must be assessed as 'pass' in order for the student to pass the course.
