Theoretical Analysis of the Reduction of Pressure Wave Velocity by Internal Circular Tubes
Michał Kubrak , Apoloniusz Kodura
Abstract
This study presents a theoretical analysis of the influence of the insertion of circular tubes into a pipeline on the rapid water hammer phenomenon. Three types of circular tubes are distinguished: a thin-walled tube, a thick-walled tube and a solid cylindrical tube. For each case, by applying the work-energy principle, a formula for the pressure wave velocity is derived. The differences between the derived formulas are analyzed. It is shown that the insertion of a tube with a low bulk elastic modulus may have a damping effect on the water hammer phenomenon, i.e., it reduces the pressure wave velocity and maximum pressure increase.| Author | |
