摘要

Study of atmospheric ice accretion on a non-rotating vertical circular cylindrical object was carried out at dry and wet ice conditions. Both numerical and experimental techniques were used during this study. 3D numerical study was carried out using computational fluid dynamics based approach, whereas experimental study was carried out at Cryospheric Environmental Simulator ‘CES’ in Shinjo, Japan. A good agreement was found between experimental and numerical results. The dimensions of the cylindrical object used to measure the atmospheric ice load on structures along this study, were selected as per the ISO12494 standard. Results provide useful information about ice growth and intensity along circular cylindrical objects at different atmospheric temperatures. This research work also provides a useful base for further investigation of atmospheric ice accretion on structures particularly circular power network cables, & tower masts installed in the cold regions.
