SG1218 Fluid Mechanics 4.0 credits

The student should be able to

• Derive the Navier-Stokes equations and explain the meaning of its terms, including the stress and deformation rate tensors
• Compute the flow field for a number of so called exact solutions
• Derive the vorticity equation and give a physical explanation of its terms
• Use the concepts of stream function and apply the Bernoulli equation
• Discuss the principles of and derive the boundary layer approximation of the Navier-Stokes equations, and to give self similar solutions of these equations including simple thermal boundary layers.
• Describe the phenomena of separation of streamlines.
• Suggest methods for measuring the velocity in a fluid.

• The student should be able to formulate mathematical models and make relevant approximations of fluid phenomena.
• The student should apply these models for simple cases and interpret the results.
• The student should gain some skill in carrying out experiments in fluids.

Completed course SG1113 or equivalent.

Recommended courses are Differential Equations and TransformsSF1683, Vector analysis SI1146 and Mathematical Methods in Physics SI1200. 

If the course is discontinued, students may request to be examined during the following two academic years.

• KON1 - Test, 2.0 credits, grading scale: P, F
• LAB1 - Laboration, 0.5 credits, grading scale: P, F
• PRO1 - Project, 1.5 credits, grading scale: P, F
• TEN1 - Exam, - credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.

KON1 - Test, 2,0 hp, grade scale: P, F

LAB1 - Lab, 0,5 hp, grade scale: P, F

PRO1 - Project, 1,5 hp, grade scale: P, F

TEN1 - Examination, 0 hp, grade scale: P, F

Requirements for final grade C-F

(KON1; 2,0 hp), examines theory and can give grade C-F.

(LAB1; 0,5 hp), performed lab with approved reporting.

(PRO1; 1,5 hp), performed project reporting by means of a poster presentation.

Requirements for final grade A-B (not mandatory)

(TEN1; 0 hp) Problem based examination, which examines skills in problem solving and application of mathematical methods.
