| Målsætning : | To give both a theoretical and practical background for the formulation and the solution of flow problems within mechanical and energy systems. A student who has met the objectives of the course will be able to: • Characterize flows and parts of flows as laminar/turbulent, viscous/inviscid, steady/unsteady or compressible/incompressible. • Describe properties of fluids and find values for the properties using tables, correlation and equation of state. • Analyze simple fluid static problems and calculate pressures and buoyancy forces. • Use Bernoulli’s equation and justify whether or not the equation is valid for a given flow. • Use the control volume method for mass, momentum and energy conservation on simple problems related to technical issues for energy and machine components. • Use dimensional analysis and explain the physical significance of certain dimensionless numbers for given flows and furthermore use these numbers in problem solving. • Choose and use correlations for forces and pressure losses for both internal and external flows. • Choose flow components and measuring techniques for an application using characteristics, correlations and estimates. • Define efficiencies and calculate energy consumption for flow processes and components. • Describe principles, performance curves and velocity diagrams for flow machines such as fans, pumps, turbines and propellers. • Use the computer software EES (Engineering Equation Solver) for the solution and the visualization of flow problems. • Read engineering literature on fluid mechanics. |
