چکیده
The effects of varying the angle of wind velocity and axis of a cylindrical icing object around all of the three mutually perpendicular axes are studied experimentally. The mass, shape and profile of ice accretion obtained in a horizontal icing wind tunnel are investigated as functions of cylinder inclination. The icing object is exposed to two types of aerosol cloud, which are created by different procedures: (i) injecting small droplets horizontally into cold air flow, (ii) injecting vertically falling large droplets into cold air flow; so that the resulting conditions simulate in-cloud icing and freezing rain, respectively. Observations reveal the effects of varying each angle on the mass, shape and profile of ice accreted under both conditions.
