After following the course the student can:
- write down the basic laws of wetting (Young Laplace law, Young equation, lubrication equation, Stokes
- Apply the physical principles of static and dynamic wetting on both homogeneous and heterogeneous surfaces;
- Analyze wetting problems and identify dominant physical principles;
- Knows about classical wetting and thin film phenomena (Rayleigh Plateteau & Rayleigh Taylor instability,
  spinodal dewetting, Bretherton problem, Huh-Scriven paradox, capillary waves);
- Discuss wetting problems and as specific questions on physical origin of phenomena.

Many physical and technological processes are affected by Capillarity and Wetting (C&W) phenomena. C&W phenomena dominate many processes in fluid dynamics on small scales. Compared to other fluid physics courses within APH curriculum this course focuses on the effect of interfaces and the related interfacial energies that control fluid flows by indirectly by imposing well-defined boundary conditions. The course focusses on fundamental concepts described within the context of fluid dynamics and discusses a variety of classical phenomena of microscopic fluid flows.

The course covers the following topics:
  • Molecular interaction force and interfacial tensions
  • Derivation of the fundamental equations of Young and Laplace
  • Wetting in external fields
  • Wetting and molecular forces (disjoining pressure)
  • Thin film flows and lubrication approximation
  • Linear stability analysis and classical instabilities (Rayleigh Plateau, Rayleigh Taylor)
  • Contact line dynamics
  • Dewetting
  • Surface tension-driven flows (Marangoni)
  • electrowetting
The course is taught in the form of classical lectures (HCs) accompanied by seminars (WCs) in which homework problems prepared and submitted by the students beforehand are being discussed.
