  • Analytical solutions of water hammer in metal pipes [Elektronski vir]. Part 2, Comparative study
    Urbanowicz, Kamil ...
    The newly derived analytical solutions of water hammer for dynamic flow velocity and wall shear stress, as well as the previously known albeit corrected pressure solutions, have been studied in ... detail. Their correctness was verified with the help of comparative tests with the results obtained with the use of a numerical solution in which a model of frequency-dependent hydraulic friction was implemented. The dynamic pressure courses were compared with the results of the experimental tests. The performed comparisons showed that the analytical models based on Brown's asymptotic extension of frequency-dependent friction function are very compatible with experimental studies for small values of water hammer number Wh. Due to the fact that the majority of unsteady water flows occur for small values of Wh < 0.1, it can be concluded that the new solutions can be safely used in engineering practice (excluding wall shear stress solution), i.e., when calculating unsteady water hammer wave dependent flows occurring in water supply systems.
