Innovative materials possess a high potential to develop new technologies for energy saving, for higher energy efficiency, and for decreasing of CO2 emissions. With respect to icing, there is a large variety of techniques used to combat ice accretion, mainly developed for aeronautical applications. Indeed icings represent a major issue and hazard on aircrafts, due to ice accretion on aerodynamic surfaces, caused by impact and freezing of atmospheric supercooled drops. Although standard techniques for ice removal are generally effective, they require the continuous supply of air, chemicals (with a direct negative impact on the environment), or electrical power. From 2008, Carlo Antonini has been part of a research project between University of Bergamo (Italy), University of Alberta (Canada), and Alenia Aermacchi (Italy), which aimed at developing an alternative strategy, called “icing mitigation”. This new strategy is based on the use of superhydrophobic, i.e. water repellent, materials, with the objective of enhancing water shedding and re-entrance in the external flow, before freezing can occur on aerodynamic surfaces, thus avoiding ice accretion. In the lecture, we will present our experimental results relative to icing wind tunnel tests and drop impact experiments, which are complementary to understand the physics involved in icing mitigation and provide rationals for engineering solutions.

The objective of the present seminar is to show the basic aspects of the free-surface flows (or Multipfase Flows) both from physical and numerical points of view. The Multiphase Flow represents one of more fascinating phenomena of Fluid dynamics. Such flows occur in a number of engineering applications involving drop impact, liquid jets, and atomization. The numerical simulation of free-surface flows represents a very challenging field due to the complex physical phenomena occurring in typical dynamics of liquid-gas or liquid-liquid interface, such as break-up, instability, and surface tension effects.

There is currently a push, in some technical fields (e.g. electronic consumer products) to "come up with the next big thing" within shorter and shorter time intervals. on the opposite end of the spectrum lie technical areas characterized by strong traditions, long development times, where innovation is slow and stakeholders may sometimes be too slow to react when external factors demand a change of pace. In both those limit cases (and everything in between) virtual prototyping is proving to be an essential tool, enabling design teams to deliver meaningful innovation to the market at the right time. Focussing on one of such "success stories", the presentation will cover a short overview on the technical features of LED lighting systems, and offer the perspective of a thermal architect on the technical and "relational" challenges one has to face when designing an "impossible" system, and how they are overcome with the help of a good simulation model.
