Abstract

The Direct Spring Loaded Pressure Relief Valve(DSLPRV) is an efficient hydraulic structure to control the waterhammer in pipeline systems. The optimization of DSLPRV was explored to consider the chattering issue of the valve disk and the surge control for the pipeline system. A surge analysis scheme, the method of characteristics, was implemented into the multiple-objective genetic algorithm to determine adjustable factors in the operation of DSLPRV. Forward transient analysis and multi-objective optimization of the adjustable factors such as the spring constant, the degree of pre-compression and the disk mass showed substantial relaxation both the surge pressure and the oscillation of valve disk in a hypothetical pipeline system. Regression analysis between surge and parameters was compared with optimization to demonstrate the potential of the developed method as a solution for computational cost issue.
