Scaling relationships for icebreaking based on analysis of a simple wedge / Donald Spencer, Richard F. McKenna.
Title: | Scaling relationships for icebreaking based on analysis of a simple wedge / Donald Spencer, Richard F. McKenna. |
Author(s): | Spencer, Donald. McKenna, Richard F. |
Date: | 1993. |
Publisher: | Hamburg: Hamburg Ship Model Basin (HSVA), Department for Ice and Environmental Technology |
In: | POAC 93 : the 12th International Conference on Port and Ocean Engineering under Arctic Conditions, 17.--20. August 1993, Hamburg. (1993.), Vol.2. |
Abstract: | Resistance of ship proceeding in level ice is combination of icebreaking processes: primarily, interaction of hull with ice resulting in failure of ice sheet. This involves ice crushing and shearing until sufficient contact is generated to fail ice sheet by flexure. Resistance is time average of these processes and thus depends on energy consumed by them. By examining energy during interaction of inclined indenter with ice wedge, certain ice-scaling laws have been derived. Influence of hull--ice friction is also examined. Results are presented showing energy balance for typical icebreaking conditions. |
