JM Burgers Center Course 2011

JM Burgers Center Course


09-13 May 2011 / Univ. Twente

Wetting and interfacial tensions play a crucial role for the behavior of fluids on length scales below the capillary length, which is typically of order 1mm. Typical application areas include well-established traditional fields such as coating technology, emulsification and oil recovery as well as recent fields such as microfluidic systems, inkjet printing technology, and immersion lithography.

The course will cover the basic theoretical models used to describe thin film flows in coating, wetting, and dewetting flows. Topics addressed during the course include wetting of patterned surfaces, superhydrophobic surfaces, contact line dynamics, theory of thin film (lubrication) flows, surface-stress driven flows, (Marangoni, thermocapillarity, electrowetting), two-phase flow micro-fluidics, drop generation.

Next to approximately 20 lectures, the program also contains ample time for discussions in the form of tutorial and in extended case studies for the evening program. Friday morning is reserved to the presentation of the results of the cases by the participants of the course.
