Thermodynamics and Fluid Mechanics

Valid for: 2022/23

Faculty: Faculty of Engineering, LTH

Decided by: PLED M

Date of Decision: 2022-04-07

Main field: Technology.

Compulsory for: M2, MD2

Language of instruction: The course will be given in Swedish

The purpose of the course is to provide basic knowledge and skills in engineering thermodynamics and fluid mechanics, with application mainly within the energy sector.

Knowledge and understanding

For a passing grade the student must

- be able to define and/or clarify in short certain basic concepts, principles and phenomena in thermodynamics and fluid mechanics
- be able to shortly account for basic relations considering properties of pure substances, mass and energy conservation, entropy generation and momentum balance, with a basic understanding of limitations and applicability
- be able to derive and account for certain technical important relations within the scope of the subject

Competences and skills

For a passing grade the student must

- be able to demonstrate a good engineering handling practice of property tables and diagrams and to be able to solve basic energy- and fluid-related problems
- be able to describe shortly, clarify and analyse certain thermodynamic processes of technical importance, with a quantitative assessment of its quality regarding the influence on the environment (entropy generation)
- be able to accomplish a complete dimensional analysis of a given dimensional problem
- be able to apply control volume analysis of the balances of mass, energy and linear momentum, for stationary flow with homogeneous in- and outlets
- be able to accomplish a basic fluid mechanical analysis of single pipe systems at stationary incompressible flow conditions, and isentropic compressible flow in nozzles

Judgement and approach

For a passing grade the student must

- be able to produce written communication, on problem-solving and the lab-report, that is well-structured and illustrative, with clear references to external sources, attention to limitations and accuracy, and which demonstrate understanding of the subject

Thermodynamics: basic concepts of thermodynamics; properties of pure substances; energy transfer by heat, work and mass; the first law of thermodynamics; the second law of thermodynamics; entropy, irreversibility and entropy generation; exergy; gas power cycles; vapor and combined power cycles; refrigeration cycles; thermodynamic property relations; phase equilibrium; gas mixtures; gas-vapor mixtures and air-conditioning

Fluid Mechanics: 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

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)

Assessment: Two written tests, mainly theory; individual problem assignments; laboratory work; and a final written examination on problem-solving. The course mark is determined from a weighted total sum, which consists of the result from the passed written examination including bonus points from approved problem assignments (if given) and the two passed tests. The graduation is determined from a special formula.

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.
