Numerical Modelling of Cavitation in an Elastic Pipe

This study is devoted to a theoretical and numerical modeling of transient vaporous cavitation in horizontal pipeline. The model approach is, essentially, based on that the column separation (CSM). basic system partial differential equations solve hyperbolic type adapts perfectly method characteristics. code, allows us, taking into account unsteady part friction term, determine at any point pipe, each instant, average piezometric head, discharge change volume vapor cavity. illustrates coupled effect presence air pockets resulting term friction, amplitude pressure wave. calculation results are good agreement with those reported literature.
