A three‐dimensional, random‐walk, ballistic model is used to simulate the density and structure of an ice accretion formed by impinging supercooled droplets. The model is calibrated using experimental observations of the ice density at the stagnation line on a fixed circular cylinder. A relationship has been established between the Macklin parameter, used commonly to relate atmospheric conditions with ice accretion density, and model parameters. The model is applicable over a wide range of growth conditions, including, in the limits, growth where the droplets freeze on impact and growth where the droplets spread over and percolate into the existing ice structure.
