MASK3610 Fluid Mechanics
Fluid mechanics forms the basis for the study of fluids, either at rest (fluid statics) or in motion (fluid dynamics). Both gases and liquids are classified as fluids, and they have a very wide range of technical applications, including turbomachinery, aerodynamics, hydropower, hydrodynamics, pipes, wind turbines, respiration etc. The course requires both an insight into physics and a sound mathematical basis. In essence, the course is a sensible compromise between theory and experimentation.
After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:Les mer om innhold og organisering.
- understands the basic concepts of fluid mechanics and recognises practical fluid dynamics problems
- is familiar with fluid properties and understands the continuum hypothesis and its area of application
- understands viscosity concepts and the effects of viscosity on flow
- knows how to use the continuity equation
- knows how to calculate hydrostatic pressure in liquids
- knows how to classify flows and give a description of laminar and turbulent flows
- knows how to use Bernoulli’s equation, and is aware of its area of application
- understands why approaches are necessary in fluid mechanics, and when they are reasonable
- knows how to calculate force and torque relating to linear and rotating flow systems
- is capable of using dimension analysis to design prototypes of a reduced scale
The student is capable of:
- using Newton’s laws to describe equilibrium and motion in fluids
- using the Navier-Stokes equation on a control volume
- formulating reasonable mathematical models to solve technical problems
- dimensioning pipeline networks
- performing calculations for the dimensioning of turbomachinery
- calculating lift and drag forces acting on rigid bodies moving relative to a fluid
- analysing flow in pipes and pipeline networks and calculating energy and pressure loss
- the student is capable of using mathematical modelling and solutions to problems in fluid mechanics to solve practical problems relating to machine design
Work and teaching methods
Lectures, video clips and exercises.
4 individual exercises
Assessment/examination and examiners
Exam form: Individual written exam, 3 hours
Examiners: One internal examiner. External examiners are used regularly.
The exam result can be appealed.
A handheld calculator that cannot be used for wireless communication or to perform symbolic calculations. If the calculator’s internal memory can store data, the memory must be deleted before the exam. Random checks may be carried out.
A grade scale with grades from A to E for pass (with A being the highest grade and E being the lowest pass grade) and F for fail is used for the final assessment.
