Similarity and Transport Phenomena in Fluid Dynamics
Course in English (28 hr, 2 credits): The course is an introduction to Lie groups and symmetry analysis, with applications to conservation equations in fluid mechanics. The course aims to provide the student with mathematical and physical tools to deal with transport equations in continuum mechanics. Emphasis is given to similarity and travelling-wave solutions.
Room: CM012. Time: 12h15-14h every Friday as of 28 September 2018.
It is highly recommended that students bring a laptop (with Mathematica or Matlab installed) for the exercises.
