A series of experiments were conducted for temperatures below 0°C, air velocities of 5, 8 and 11 m s-1, with the goal of studying the structural characteristics and sublimation of ice structures grown over cylindrical rotating collectors. The results show that the accreted ice presents structures similar to lobes. A connection between the surface characteristics of the accretion and the environmental conditions was established. It was also found that the size and density of the lobes accreted on the surface do not affect the ice sublimation rate when the sublimation process occurs in free convection conditions.
