Series Statement:
CRREL Report 88-15
Content:
The main points covered are: (1)modeling criteria for ships in ice, which must take into account the presence of a solid boundary at the water surface; (2) types of model ice used in various tanks-saline ice, urea-doped ice, EG/AD/S ice and synthetic ice; (3) techniques for growing model ice sheets, and achieving and monitoring the required ice properties; (4) limitations of both model ice and property measurement techniques; (5) model testing procedures for EHP and SHP tests and their limitations; (6) comparison between model test results and available full-scale trials data; (7) existing empirical and analytical or semi-analytical algorithms for predicting ship performance in level ice; (8) current research at CRREL and other research facilities to improve modeling techniques and data interpretation; and (9) novel bow designs for ice-transiting vessels.
