Omission of frequency-dependent hydraulic resistance (skin friction) during modelling of the water hammer phenomenon is unacceptable. This resistance plays a major role when the transient liquid flow occurs in rigid-walled pipes (steel, copper, etc.). In the literature, there are at least two differ ...

Modeling transient pipe flow in plastic pipes with modified discrete bubble cavitation model

Oznake: retarded strain;cavitation;water hammer;unsteady friction;method of characteristics;
Most of today's water supply systems are based on plastic pipes. They are characterized by the retarded strain (RS) that takes place in the walls of these pipes. The occurrence of RS increases energy losses and leads to a different form of the basic equations describing the transient pipe flow. In t ...
