General Information

Depth of study relative to the degree requirements: Second cycle, in-depth level of the course cannot be classified
Elective for: F4, F4-bem, Pi4-bem
Language of instruction: The course will be given in Swedish

Aim

The purposes of this course are to provide extended understanding of technical and fundamental relations and phenomena, and to provide a general survey of problem-solving methods, within the field of basic fluid mechanics.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to define shortly and/or clarify certain basic concepts, phenomena and measurement techniques in fluid mechanics
• have a comprehension of and be able to account for at some detail some basic and more advanced fluid relations
• have a comprehension of the laws of similarity, and their practical importance i scaling
• have a comprehension of the mechanisms of flow resistance and flow-induced forces considering technical aero- and hydrodynamic design

Competences and skills
For a passing grade the student must

• be able to assess reliability and accuracy of input data and calculated results
• be able to apply control volume analysis of the balances of mass and linear momentum, for stationary flow conditions
• be able to accomplish a complete dimensional analysis of a given dimensional problem
• be able to carry out elementary analysis of fluid drag and lift on immersed bodies and one- and two-dimensional compressible flow, and a detailed fluid analysis of simple and multiple-pipe systems, at stationary, one-phase, incompressible conditions
• be able to search for, compile, analyse and critically review information concerning a specific problem within fluid mechanics

Judgement and approach
For a passing grade the student must

• be able to demonstrate written communication skills that are well-structured, learning-oriented and illustrative concerning project report and other written examination
• be able to communicate verbally and in writing with the teachers of the course as well as with the students peers, on matters considering basic phenomena and problems in fluid mechanics

Contents

Scope of fluid mechanics and fluid properties; viscosity; basic fluid statics; the Bernoulli equation; fluid kinematics; finite control volume analysis; basic differential analysis of fluid flow; similitude, dimensional analysis, and modelling; viscous flow in pipes; flow over immersed bodies; one-dimensional isentropic compressible flow through nozzles. In addition, in-depth studies are included in some sub-area of flow mechanics.

Examination details

Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: Assessment of individual (written) home exercises, a final written examination, which consists of a theory part (without means of assistance) and an open-book problem-solving part, and written report and oral presentation of a project work. The course mark is determined the result from the written examination, the project report and (if any) bonus points from approved problem assignments. The graduation is determined from a special formula. The final grade is based 60% on the exam and 40% on the project assignment.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
