MASK3610 Applied Fluid Mechanics Course description

The course deals with theoretical and practical aspects of applied fluid mechanics. Some of the vital topics covered are boundary layer concept, governing equations, incompressible flows, compressible flows, high speed flows, internal flow, external flow, dimensional analysis, and introduction to computational fluid dynamics.

The elective course is initiated provided that a sufficient number of students choose the course.

Passed the course Mathematics 1000, Mathematics 2000, and Physics and Chemistry and Mechanics.

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:
