ESR 13: Development of icing strategy for wind sensors

FT Technologies, Sunbury-on-Thames (UK)

Researcher: Theodoros Dimitriadis

Supervisor: Tanmoy Maitra

Project goals:

The project will aim to develop an icing strategy for ultrasonic wind sensors. The strategy will exploit greatly different coatings, the passive mechanism, to reduce ice nucleation and adhesion that leads to minimize the need of existing active (heating) strategy in the wind sensors. The projects will be organized into main phases:

Commercial and state-of-art hydrophobic coating technologies

  • Ranges of different commercial hydrophobic coatings such as perfluoro alkoxy industrial coatings, polyurethane and polyurea based coatings will be studied on device scale
  • Application and designing of i-CVD organic polymer coatings will be studied on device scale in collaboration with Graz University of Technology.

Coating characterizations

  • Thickness and chemistry of coatings will be characterized
  • Wettability and icing performance of coatings will be characterized in collaboration with UNIMIB

Validation tests of coatings

  • To evaluate the coatings performance, there are many tests will be performed in laboratory artificially that simulate real world conditions. Those ASTM and ISO standard tests includes, but not limited: Defense standard icing tests (DEF- STAN), weathering tests (including UV), corrosion tests and rain tests.
