| Abstract: | Using the results of the resistance test, propeller open water test, self-propulsion test for five geosims models (the lengths of models were 3.1481m, 3.6170m, 4.2500m, 5.1515m and 6.5385m respectively) and the velocity distribution at the propeller plane for the three models of 3.1481m, 4.2500m and 6.5385m, the authers studied the scale effects of resistance, open water propeller and self-propulsion factors. The satisfactory results for the scale effect of wake survy were obtained.Finally, the correlation analysis was corried out separately using several correlation methods with the data of trial, and the effects of the adopted different correlation method for the resistance and self-propulsion factors were determined. |
| Keywords: | Resistance and propulsion series test scale effect wake survy correlation analysis. |
