MASK3610 Applied Fluid Mechanics Course description

The course deals with theoretical and practical aspects of applied fluid mechanics. Some of the vital topics covered are boundary layer concept, governing equations, incompressible flows, compressible flows, internal flow, external flow, dimensional analysis, and introduction to computational fluid dynamics.

The elective course is initiated provided that a sufficient number of students choose the course.

Knowledge

The student:

• is capable of applying and processing knowledge of science and technology to solve mechanical problems
• is capable of proposing technical solutions, and analysing and quality assuring the results

Skills

The student:

• is capable of translating knowledge into practical solutions
• masters mechanical modelling and analysis methods
• is capable of quality assuring and analysing results obtained in a project
• is capable of documenting and discussing results, both orally and in writing, so that they shed light on an issue
• is capable of obtaining literature and other background information of relevance to the project, and writing reports based on standardised methods

General competence

The student:

• is capable, in an independent and systematic manner, of carrying out an engineering assignment based on a practical industrial or research-related issue
• masters both independent work and team work, including planning and implementation of engineering projects
• has the ability to place their own work in a wider engineering context

No requirements over and above the admission requirements.

After completing the course, the student is expected to have achieved the following learning outcomes defined in terms of knowledge, skills and general competence:

Knowledge

The student:

• understands the basic concepts of fluid mechanics (such as boundary layer, continuum hypothesis, viscosity, conservational laws) and recognizes practical fluid dynamics problems.
• knows the difference between system approach and control volume approach and is able to explain the difference between Eulerian and Lagrangian description of fluid flow.
• knows how to use the fundamental governing equations of fluid dynamics - (continuity, momentum and energy equations) and is aware of its area of application.
• is capable of using dimension analysis to design prototypes of a reduced scale.
• understands the basic theoretical background of CFD and is able to perform simple CFD analysis.
• understanding of the various physical phenomena associated with the internal flow and external flow over common geometries.

Skills

The student is capable of:

• making simple calculations of velocity, pressure, temperature and shear stress for incompressible flows.
• formulating reasonable mathematical models to solve technical problems.
• calculating lift and drag forces acting on rigid bodies moving relative to a fluid.
• analyzing flow in pipes and pipeline networks and calculating energy and pressure loss.
• performing basic CFD analysis and comprehend the results of CFD.

General competence

The student must:

• be capable of using mathematical modelling and solutions to problems in fluid mechanics.
• be able to use CFD tool to solve relevant problems related to fluid flow

Lectures, CFD lab exercises and assignments.

5 of 7 compulsory assignments must be approved.

The coursework must be approved before the student can take the exam.

The tasks are delivered in Canvas.

Exam autumn 2021 due to Covid-19:

Individual digital home exam, 3 hours.

The exam result can be appealed.

[Exam earlier:]

1. Portfolio (counts 50%). The portfolio consists of:

• 2 individual reports (word limit 1000-2000) based on CFD analysis of the engineering components.

2. 3 hour written exam (50%).

The exam results can be appealed.

In the event of a resit or rescheduled exam, an oral examination may be used instead. In case an oral exam is used, the examination result cannot be appealed

Aid autumn 2021:

All aids allowed, except communication with others.

[Aid earlier:]

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.

Grade scale A-F.

The students shall apply knowledge and skills they have acquired in the study programme to a realistic engineering problem. They shall demonstrate the ability to further develop their knowledge and skills in theoretical and/or practical problem-solving. The students shall demonstrate a responsible and ethical approach in their professional expertise. The course builds on the first and second years of the study programme.

Students must be registered in the third year and have completed at least 100 credits from the first and second years of the programme by 1 October before they are assigned a topic for their bachelor’s thesis.
