Abstract
Numerical study of atmospheric ice accretion on a non-rotating circular cylinder was carried out at dry rime ice conditions. To validate the numerical model, results were compared with the experimental data obtained from CIGELE atmospheric icing research wind tunnel (CAIRWT). A good agreement was found between experimental and numerical results. Numerical study showed that selection of appropriate numerical model of ice density and droplet size distribution is important, as these can significantly varies the simulated ice growth. Parametric study at different air flow velocities and angles showed a significant change in ice accretion on circular cylinder. This research work provides a useful base for further numerical investigation of atmospheric ice accretion on circular power network cables installed in the cold regions like arctic and alpine.
