Academic content
- Purpose
- To give a theoretical background for understanding, formulation and solution of flow problems within mechanical and energy engineering.
- Learning outcomes
- After completing the course, the student can: 1. Describe fluid properties and characteristics. 2. Describe the classification of flows and distinguish laminar and turbulent conditions. 3. Perform basic calculations of static pressures and forces. 4. Describe the concept of volume control and its application. 5. Describe the terms in the Navier-Stokes equation. 6. Describe and perform basic applications of the Bernoulli equation. 7. Describe the concept of dimensionless numbers and their basic application. 8. Describe the concept of the viscous boundary layer and the respective pressures and forces and apply for the solution of basic problems. 9. Describe correlation-based equations for forces and pressure losses and apply for basic problems. 10. Describe efficiencies and energy losses in flows. 11. Perform basic calculations for losses in pipe flows for the example of water supply systems and the circulation heating systems. 12. Describe basic principles of flow machines – pumps, turbines and propellers – and their basic characteristics. 13. Describe efficiency characteristics of turbines and pumps and perform calculations for basic examples.
