Navier-Stokes solutions for accelerating pipe flow
Kamil Urbanowicz, Anton Bergant, Michal Stosiak, Adam Deptuła, Mykola Karpenko
Pregledni znanstveni članek
Oznake: Navier-Stoksove enačbe;analitične rešitve;pospešujoč tok;cevni tok;kanalski tok;Navier–Stokes equations;analytical solutions;accelerated flow;pipe flow;
This paper reviews analytical solutions for the accelerated flow of an incompressible Newtonian fluid in a pipeline. This problem can be solved in one of two ways according to the (1) imposed pressure gradient or (2) flow rate. Laminar accelerated flow solutions presented in a number of publications ...

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 ...
