Formation and sublimation of ice structures over cylindrical collectors

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 lobe-number density of the ice accreted on the surface do not affect sublimation rate when the sublimation process occurs in free convection conditions.
