Discrete-drop mode of ice accretion on a cylinder in transverse supercooled flow

A physicomathematical model is developed for spatiotemporal evolution of an ice layer growing upon solid body interaction with individual droplets that slide along the body surface and harden on it, resulting in two-dimensional roughness (lumpy ice). The case of a cross-flow circular cylinder illustrates the calculation results for a set of control parameters typical for ground-based experiments in an aero-refrigeration wind tunnel.
