Evaluation of the Immersion Ratio Effect on the Performance of the Semi-Submersible Propeller

Analysis of the semi-submersible propeller due to the diversity and complexity of flows, geometric parameters and come up with different physical phenomena such as the free surface treatment, spraying water, ventilation, surface tension and so the complexity is high. In this article for a sample of the semi-submersible propeller geometry determines with constant taking into account many parameters and factors, the effect of the thrust of the propeller immersion was studied and analyzed. For the semi-submersible propeller section profile, a commercial profile is used. Considering the effect of immersion in the semi-submerged propeller, the propeller in fixed speed and flow in different immersion depth has been investigated. According to obtained data with increasing immersion, raise the multiplier can be seen in the semi-submersible propeller thrust
