Abstract:

Based on the practical needs of engineering projects, this paper explores how to obtain different types of uniform and repeatable ice layers on the surface of vertical test object. Firstly, a set of spray icing experiment platform is built, including suitable air atomization nozzle and water and gas supply equipment, the cold storage that can provide sufficient cooling capacity, and various kinds of sensors with corresponding range to monitor the temperature, pressure and other parameters during the experiment. Then, the icing characteristics of nozzle spray are studied based on the platform. By adjusting the water and the gas inlet pressure of the nozzle to change the spray water flow rate and the spray particle size, and matching different ambient temperature, different icing types are obtained on the surface of the test object, and the experimental repeatability is verified for the corresponding working conditions. Finally, the icing effect required by the project is explored to provide support for the selection of project design and implementation scheme.

Key words: icing experiment, cloud simulation, icing type, air atomizing spray, smooth and flat glaze ice
