The course aims to provide the students with fundamental knowledge and understanding about mathematical modeling in fluid mechanics. One of the aims is to let the students develop basic technical skills, and critical thinking, needed when modeling and solving mathematical problems in different settings. Special attention will be paid to help the students to develop communication skills necessary for teamwork. The course covers topics and provides learning skills that are important in applied mathematics and scientific calculus.
Lectures: Presentation of the theory described in the course program, with teacher-student direct interaction, to ensure a full understanding of the subject.

Type of Assessment
Final oral examination. A number of questions are posed. The oral examination is designed to evaluate the degree of understanding of the theory presented in the course. In the assessment, special attention is paid to communication skills, critical thinking and appropriate use of mathematical language.
