A Method of Scaling for Ship-Ice Model Tests
A dimensional analysis of the problem of vessels transiting level continuous ice is presented. Resistance is divided into components and each analyzed to identify dimensionless terms relevant to the individual component. These expressions provide a framework for scaling ship-ice model test results. A workable subset of scaling requirements for a three component division of the problem is derived from the general case. Some experimental results are presented demonstrating the utility of the method. It is shown that it may be possible to compensate for poor scaling in ice properties by scaling each component based on its own law of similitude.
