Abstract
Abstract. Pressure surges during pipe transient flow are important to the design and maintenance of the pipeline structure. This work argues about the effect of the pipe roughness on them. The analysis is carried out by the computed responses of a robust one-dimensional mechanical model of turbulent pipe flows. The pipe roughness is found to be relevant as pressures responses differ considerably. Such influence is herein justified by the fact of the pipe roughness generates different turbulent viscosity structures which are substantial to the overall fluid transient behavior.
