Samenvatting
This paper reports the development and application of an elastic-column model for rapid
draining of pipelines. The water-hammer equations with a moving boundary are used to
model the emptying process, and the SPH method is employed to solve the governing
equations. The image particle method is used to ensure complete kernel support and impose
boundary conditions, simultaneously. The velocity-Verlet method is applied for time
integration to enhance accuracy. The developed SPH-based elastic-column model clearly
shows the transient effect in the emptying process, and it is a promising tool for the
simulation of rapid emptying of pipelines with undulating elevation profiles.
