SG1217 Fluid Mechanics, Basic Course

Completed courses SG1132 Mechanics I with project and SF1626 Multi-variable analysis.

Hydrostatics. The kinematics of currents. Streamline and particle path. Dimensional analysis. Frictionless incompressible flow. Bernoulli's equation. The control volume formulation of the continuity and momentum equation. Stream function for two-dimensional flow. Irrotational flow and velocity potential. Viscous flow: laminar and turbulent flow in channels and boundary layers, separation.

Laboratory exercises: Two compulsory laboratory exercises, which are carried out in groups of four students. Each laboratory session begins with a brief oral test to check that all group members are prepared. The laboratory report can be completed at the laboratory session. In addition to the teaching, some demonstrations are carried out in the fluid physics laboratory illustrating various flow phenomena.

Project assignment: Mandatory project assignment on the flow phenomena around a two-dimensional wing profile, especially with regard to the determination of the lifting force. The labs are an integral part of this project assignment.

After studying this course the student should be able to:

• apply the conservation laws for mass and momentum in various technical flow problems in order to analyze the interaction of forces between solid bodies and flowing/stationary fluids,
• identify and apply mathematical models for estimating fluid mechanical quantities,
• conduct a comparative analysis between the results of a mathematical model and the corresponding empirical data.
