Noise may occur during switching the diverter. To reduce the noise, this investigation uses computational fluid dynamics (CFD) software ANSYS Fluent with the dynamic layering method and the user defined function (UDF) to simulate the flow field of the pressure-controlled diverter. The simulations are focused on analyzing the transient flow field and the resultant pressure that causes the diverter movement. Furthermore, the system dynamics method is used to construct the dynamic model and the state equations of the diverter system. By solving the state equations, the velocity and the force of moving part, the response time, and the flow rate of shower can be determined for a wide range of parameters. Based on the numerical results, the system dynamic analysis is employed to obtain the key design parameters and the appropriate values. The results of system dynamic analysis indicate that a reduction of the gap in the secondary chamber of the diverter can decrease the velocity of the moving part as well as increase the force of the moving part, and thereby prevents the serious noise and the leak of faucet outlet. 陳志敏 2012 學位論文 ; thesis 38 zh-TW |
