1. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

2. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements
Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER
3. Development and Test of an Imaging Instrument for Measurement of Water Droplets in Icing Conditions
Sammanfattning : Structural icing is a persistent challenge for the production of renewable energy from wind. It is mainly caused by supercooled atmospheric droplets of water, which are very common in cold climates. In the most exposed wind parks in Sweden, more than 10 per cent of annual energy production can be lost. LÄS MER
4. Measurements for winter road maintenance
Sammanfattning : Winter road maintenance activities are crucial for maintaining the accessibility and traffic safety of the road network at northerly latitudes during winter. Common winter road maintenance activities include snow ploughing and the use of anti-icing agents (e.g. road salt, NaCl). LÄS MER
5. Snow deposit melt and atmospheric icing : analysis and modelling by weather station data
Sammanfattning : Snow deposit melt should be included when dealing with urban run off. Every winter structures experience atmospheric icing. The objective was to develop physically sound models based on weather station data for estimating snow melt and atmospheric icing. LÄS MER
