Abstract

The modelling of transient cavitation is described in this chapter by considering column separation modelling where FSI and gas release are taken into account. As detailed for water hammer modelling, transient in straight pipeline is caused by fast closure of shut-off valve. Both vaporous and gaseous cavitation are considered in the numerical models. 

Keywords: Cavity; Collapse; Column separation; Discrete model; Gas release; pressure pulse, Vaporous cavitation.
