Abstract

 Research on the evolution of technology for the use of fluid flow caused by propeller thrust, it is necessary to develop the most optimal position to produce maximum water discharge. In previous research on the shape and variation of the vertical position of the inlet nozzle on the utilization of the ship’s stern flow as a source of cooling water for the ship’s main engine. This research carried out an analysis carried out is by using an ellips intlet nozzle as the utilization of the stern flow of the ship. This study aims to determine the difference in the volume of water generated from several horizontal positions of the nozzle inlet. In this study the method uses is an experimental method that analyzes the horizontal distance of the inlet nozzle to the propeller at 0,7R propeller blade that is, 5 cm, 7,5 cm, 10 cm, 12,5 cm, 15 cm and using the computational dynamic fluid (CFD) method to analyze the optimal horizontal distance of the inlet nozzle to produce the highest water flow rate in each test case. Based on the research result, it shows that the optimal horizontal distance of the inlet nozzle to the propeller is a distance of 7,5 cm. As from the water flow generated in the experiment is 13,38 liters/minute and the water flow generated in the computational simulation is 14,24 liters/minute. In that case, it can be concluded that the effect of the horizontal distance of the inlet nozzle on the propeller greatly affect the flow of water produced. In process data collection it is better to use commonly uses on ship.
