The impact of the ship shape and draught on ices distribution in the zone of its propulsion-steering complex
Abstract
The article deals with the study of the nature of interaction of a travelling vessel’s hull with ice cakes and small ice cakes of different thickness and concentration in the ice channel with the use of CAE technologies. The focus is on studying the distribution of ices in the area of traditional propulsion-steering complex location at variation of dimensions, hull shapes and ship draught.Qualitative features of such interaction of the vessel with the water ice environment are noted. The statistical analysis of the obtained experimental data on the assessment of design, dynamic and ice factors impact on ices concentration in the area of their contact with a propulsion-steering complex was carried out. The quantitative forecast of such an impact in the form of the multifactorial regression equation is given.
