The aim of this Bachelor’s thesis was to optimize the pressure loss for an already built sprinkler valve for a high pressure water mist system. The purpose of optimizing the pressure loss through the sprinkler valve is to gain better functionality characteristics for the high pressure water mist system in both land and marine based applications.
In order to, obtain a good understanding of the high pressure water mist technology and why it is preferred especially in marine applications, the conventional sprinkler system is introduced and discussed briefly in the beginning. Also, the regulations and standards as well as the classification societies are introduced for the high pressure water mist system. It is important to develop a good understanding of fluid mechanics since it is widely used in the design of modern engineering systems. Therefore, the fluid mechanics for internal flow and the concepts regarding the pressure loss effects are discussed and explained comprehensively.
The research started by conducting an extensive feasibility study for a sprinkler valve, in order to allocate the problem as well as to compare the results with the results obtained from the development work. The experimental results unveiled the deviation of the theoretical based results, and this was due to a simplified approach and hypotheses made in theory.
The feasibility study resulted in several potential design concepts for the sprinkler valve, which were simulated by utilizing the Computational Fluid Dynamics (CFD) approach. Based on the obtained results from the simulation, one concept design was upgraded and field tested in the sprinkler valve.
In conclusion, the scope of the project was achieved by the final concept design. The development work concluded in high optimization level, which will in the future bring several enhanced functionality properties for the water mist system.
