The influence of cross-sectional shape
of a submerged body on wave formation and ice-breaking
Abstract: When solving the problem of motion of a submarine vessel near the ice surface, the hull of a submarine, which is of a complex geometry, is usually replaced by a rotation body of a simplified shape while preserving its main characteristics (elongation and displacement). In turn, the shape of cross section of the hull can have a significant influence on the parameters of flexural gravity waves generated by submarine vessel’s motion. The authors present an experimental research of influence of cross section’s shape on the deflection and the length of flexural gravity waves. Experiments for which three models were made with the same characteristics, but different shape of cross sections, were carried out in the ice tank. In the process of towing the models velocity was determined and the profiles of deflections in the ice cover were registered. Scale modeling was 1:120. The experiments allowed us to find dependencies of parameters of flexural gravity waves on the characteristics of the models. For the first time using model experiment, influence of cross-sectional shape of a submerged body on the ice-breaking capacity of flexural-gravitational waves is determined.
Keywords: submerged body, ice cover, flexural-gravity waves.
