Abstract

Pressure transients in pipes with turbulent flow have classically been simulated using numerical techniques such as the method of characteristics. An alternative method utilizing an inverse frequency algorithm has recently been introduced for smooth pipe and determined to be computationally fast compared to the method of characteristics and in some cases more accurate. In addition, comparisons with experimental water hammer data has verified that the inverse frequency method is accurate out to Reynolds numbers of 15,800. This thesis investigates a comparison or the inverse frequency and method of characteristics methods for Reynolds numbers out to 200,000 for smooth pipes.
