Similarity and Transport Phenomena in Fluid Dynamics
Course in English (28h, 2 credits): 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: ME 0 1418. Time: 12h15-14h every Friday as of 18 September 2020. It is highly recommended that students bring a laptop (with Mathematica or Matlab installed) for the exercises.
