Purpose

1. Simulate variety of harsh ocean environment conditions: cold temperatures, high winds, and precipitation that is repeatable and controlled.
2. Marine Icing and Atmospheric Icing.
3. Wave impact spray generation resulting in freezing spray; with and without wind assist.
4. Modelling impact forces.
5. Ocean, Naval, Aeronautical, Civil, Mechanical applications and other “harsh” conditions.

Wind Tunnel Air Temperature and velocity:	-20 C < T < 20 C; 0 < U < 30 m/s
Wind Tunnel Spray System:	Simulate atmospheric precipitation
Wind Tunnel Floor panels:	Removable
Wave Basin:	Ambient temperature, fresh water, seawater salinity

Simulations:	Wave impact spray generation resulting in freezing spray; ice accretion simulation; modelling impact forces.

Objectives

Determine how:

• Droplet size affects the amount of ice accretion
• Temperature of sea, air and vessel surfaces effect the icing process
• Sea spray ice accretion occur on different surfaces
• Gravity and salinity effect marine icing phenomena

Determine how to:

• Monitor parameters for accurate prediction of icing
• Monitor the amount of icing on a given structure
• Scale results of model scale icing experiments to full scale
• Develop de-icing strategies
