AERODYNAMICS AND COMPRESSIBLE FLOW

MMVN01

Credits: 7,5. Grading scale: TH. Cycle: A (Second Cycle). Main field: Technology. Language of instruction: The course will be given in Swedish. Optional for: M4bem, M4en. Course coordinator: Christoffer Norberg, Christoffer.Norberg@energy.lth.se and Johan Revstedt, Johan.Revstedt@energy.lth.se, Energy Sciences. Prerequisites: MMVF01 Thermodynamics and Fluid Mechanics. Recommended prerequisits: FMA430 Calculus in Several Variables. Assessment: Assessment of individual (written) home exercises, lab-reports, written and orally presented group exercise, and a final written examination, which consists of a theory part (without means of assistance) and a written theory test (without means of assistance). The course mark is determined from a total sum, which consists of the result from the passed written test and bonus points (if any) from approved problem assignments. The graduation is determined from a special formula. Home page: http://www.energy.lth.se.

Aim
The purposes of this course are to gain extended understanding and knowledge within the area of aerodynamics and compressible flow and to provide a general understanding of aerodynamic design of immersed bodies, in particular wings and other lifting surfaces.

Knowledge and understanding
For a passing grade the student must

be able to define shortly and/or clarify certain basic and more advanced concepts and phenomena within the area of aerodynamics and compressible flow; for example, center-of-pressure, circulation, velocity potential, the Kutta-Joukowski theorem, vortex sheets, mean chord line, the von Kármán log-law, boundary-layer separation, Mach wave, and normal shock wave
have a comprehension of and be able to account for at some detail some basic and more advanced aerodynamic concepts; for example, the Lanchester-Prandtl lifting-line theory and the Prandtl-Meyer theory of oblique shock and expansion waves
have a comprehension of the mechanisms of flow resistance and flow-induced forces considering technical aerodynamic design

Skills and abilities
For a passing grade the student must

be able to assess reliability and accuracy of input data and calculated results
be able to carry out elementary analysis of laminar and turbulent boundary layers, fluid drag and lift on immersed bodies, and one- and two-dimensional compressible flow
be able to carry out a detailed fluid analysis of subsonic and supersonic flow around lifting surfaces (wings) and compressible flow in nozzles and ducts

Judgement and approach
For a passing grade the student must

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

be able to demonstrate written communication skills that are well-structured, learning-oriented and illustrative (group report and other written examination)
