Method of Ice Distribution and Data Processing for Ship Ice Resistance Experiment in Broken Ice Field

A method of ice distribution and data processing for ship ice resistance experiment in broken ice field, comprising the following steps:

• S1. uniformly distributing ice floes in a broken ice field with eliminating overlapped ice floes, and recording pre-experiment data;
• carrying out a ship ice resistance experiment in the broken ice field, and recording experimental data;
• S2. repeating step S1 at least three times;
• S3. based on the segmentation hypothesis and stable state requirement in ITTC ice testing guidance document, dividing the broken ice field into multiple subdomains;
• S4. conducting an outlier data point judgment for the experimental data corresponding to each subdomain to discard the experimental data corresponding to abnormal subdomains, and conducting uncertainty analysis for the experimental data corresponding to remaining subdomains;
• S5. conducting an image correction for pictures of the broken ice field in the pre-experiment data and dividing the pictures by subdomains to obtain subdomain pictures, and calculating an actual coverage rate of subdomain corresponding to each subdomain picture;
• and
• S6. according to the actual coverage rate and design coverage rate of the subdomains, modifying ice resistance in the experimental data corresponding to each remaining subdomain to obtain a final ice resistance corresponding to each remaining subdomain.
