Abstract

Ejector is a static pump which is worked by a vacuum principal. A vacuum which is happened in the ejector affect the performance and the ability of suction on the secondary mass flow section. A vacuum ejector in the fresh water generator affects the amount of fresh water which is generated. The objective of this research is to know the affection of variation in the outlet diameter of the nozzle towards secondary mass flow, especially on the air suction section (vacuum). In this research, an analysis has been done in a fresh water generator (FWG) with three alternative design of the outlet diameter of the nozzle using Computer Fluid Dynamics (CFD) method to get the optimal performance. The inlet pressure of primary flow is regulated to be steady at 3 bars. The variations of the diameter outlet of the nozzle are 4, 6, and 8 mm. The distance between the edge of the nozzle with outlet flow of the pipe is made at a settled position. The edge of the nozzle is at 3 mm inside the outlet flow of the pipe measured from the inside edge of the pipe. The result of CFD method is shown that on the variation of the outlet diameter of the nozzle 8 mm has the biggest mass flow (4.6838048 kg/s) between 4 and 6 mm. The implication of this research is that the outlet diameter of the nozzle 8 mm has the maximum value of a vacuum.

Abstract

Air compressors are auxiliary machines on board that produce compressed air on board. Compressed air is used as starting air for the main engine when the ship is about to perform maneuvers. On the MV. Maluku 8 there has been a leak in the air reservoir safety valve, where the pressure in the bottle is lacking while the air compressor is working continuously, this will result in damage to the air compressor. This research was conducted using descriptive methods and data collection techniques and interviews that aim to describe the actual situation in fact encountered in practice. Based on the results of the research, while the writer was carrying out the practice, a safety valve leak was found in the air tube (reservoir) due to dirt in the valve. The problem solver of this problem is to provide parts to the savety valve. To maximize performance and prevent air leaks in the compressor system at MV Maluku 8, there are several recommended corrective actions to expedite the performance of the main engine, including maintenance of the air compressor according to the provisions applied and proper PMS implementation.
