| Målsætning : | To give both a theoretical and practical background for the formulation and the solution of flow problems within engineering 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. • Use the computer software EES (Engineering Equation Solver) for the solution and the visualization of flow problems. • Analyze turbomachinery such as pumps and turbines. • Analyze compressible flow. • Read engineering literature on fluid mechanics and fluid machinery. • Apply the topics of the lectures to practical problems through project work in groups. • Learn new topics in fluid mechanics, turbomachinery and CFD through guided projects. • Organize project work in small groups. • Write a professional project report containing the engineering analysis and the solutions of the problems posed in the assignments. |

| Hovedindhold : | Classification and properties of fluids. Fluid statics. Introduction to the basic principles for conservation of mass, momentum and energy for fluid mechanical systems. Conservation equations in control volume form. Inviscid flows: Bernoulli"s equation. Static, dynamic and total pressure. Dimensional analysis, modeling and similarity. Introduction to measurement techniques in fluid mechanics. Head loss in pipes and pipe systems. Drag and lift. Turbomachinery, including pumps and turbines. Compressible flow. Introduction to CFD using FLUENT or COMSOL. | ||
| Undervisningsform : | The pedagogy of the course is “problem-based learning”. Approximately half of the time allocated to the course will be used in guided project work in groups. The course projects will give the students an opportunity to apply basic concepts learned in the class to real-life problems, and to learn new topics in fluid mechanics, turbomachinery and CFD that are not covered in the lectures. There will be introductory and summing up lectures and the students will work in small groups with projects, problem solving, simulations and case studies. |
