EFFECT OF POLYMER ADDITIVES ON PROPELLER PERFORMANCE

Open-water tests were performed with a model propeller in a water flume with polymer injection ahead of the propeller disk. The thrust and torque were measured at a number of revolutions and at one rate of flow of water. The analysis of the tests indicates a definite reduction of propeller thrust and an increase of torque when polymer additives were injected ahead of the propeller disk, resulting in the reduction of the propeller efficiency "in the open". For an average concentration of 20 ppm of the additive passing through the propeller disk, the efficiency was reduced by approximately 5 percent.
