Abstract
In order to be able to predict the local ice accretion rate, or the icing profile on any surface it is neccessary that a model be available, which helps in determining the local impingement values of water droplets on the object. Two models have been developed. One model determines the potential and the velocity field around any arbitrary object. The second model determines the trajectory of the water droplets in the presence of a potential field. The two models have been combined to form a general trajectory model capable of tracking water droplet trajectories around any arbitrary object. The object considered is approximated by the method of source panels.
Effects of gravity (weight of the droplet) and the boundary layer effects near the wall are studied.
The runs are made with an ambient temperature of 263 K and with relative air velocities in the range of 30-120 m/s. It is shown that the effects of gravity and boundary layer are not appreciable on the overall collection efficiency but have an effect on the local values.
The developed trajectory model is then used in conjunction with an already existing ice accretion program to predict the accretion of ice on the surface.
