Surge analysis in piping systems analysis of valve characteristics

Abstract

Analysis of pressure transients is a crucial factor in determining the upstream and downstream pressures acting at various time steps along the length of the pipe. The method of characteristics is a useful tool and is implemented on a computer software to evaluate the surge occurring in pipelines. These surges are largely influenced by the valves present in the piping system. By studying the characteristics of these valves we can identify the upsurge and downsurge. In this paper, we focus upon the optimization of the valves, in order to minimize the pressure transients caused by it.
