Purpose
• Study the ice build-up
• Study the effect of ice on the aerodynamics
• Study the flow around the iced blade – flow visualization
• Compare results with numerical programs and other studies
2 7 February 2012

Wind Tunnel Tests - Preparation
9 7 February 2012
• Due to unexpected circumstances
– Some velocity tests – test the set up
– Flow visualization – with oil based smoke generator and laser

Wind Tunnel Tests – Further Plans
13 7 February 2012
• Dry test:
– Test of the set-up both aerodynamics and pressure distribution, flow visualization
• Ice test:
– Test of ice build up with different velocity and temperature
– Changes of aerodynamics as a function of time and amount ice
– Flow visualization
