STUDY OF DRY ICE GROWTH ON DUPLEX CYLINDERS

A study of dry ice growth on bundled (duplex) cylinders has been performed using icing wind tunnel experiments and computational fluid dynamics (CFD) numerical simulations. The aim this is to "fill the gaps" in works Wagner (2010) Qing et al. (2018). simulations cover a range possible conditions by varying operating speed, median volume diameter, for some cases-the angle incidence between cylinders. obtained results 0° AoA show that accreted masses ratio leeward windward cylinder varies from ~ 100% 30%. decreases with increase speed and/or diameter. For cases non-zero AoA, become approximately equal, when large enough produce vertical separation equal or greater one
