碩士 / 國立交通大學 / 機械工程系所 / 96 / The self contained underwater breathing apparatus - SCUBA set ,consist of compressed air tank and pressure regulator .The development of scuba diving nowadays is based on the invention of regulator. The pressure of compressed air carried by diver must be reduced to the pressure as in environment by regulator before he or she can breath in.If the regulator fail in the water or it can’t supply the enough air for diver, the lives of diver would be in serious danger .So the performance and stability of the regulator concern the life of divers .Until nowadays, the design of regulator is depend on the experiences of the designers .Try-and-error is required to get the better results.
In this project, using the Mold-Flow Analysis Software- FLOW-3D, simulation of the air flow in the regulator will be used and analyses of the key factors influence the performance of the regulator will be idenfied. Besides, we can predict the index performance of regulator by using the analysis result.
Contrary to the tradition process, the performance can be predicted bfore a proto-type is made for experiment when design a new regulator. Therefore, the simulation process by using of FLOW-3D can effectively reduce the time of develop products.
In addition, utilize the results of simulation to improve the regulator for a better performance.
