The introduction of non-linear, shock-capturing schemes has improved numerical predictions of hydraulic bores but significant numerical oscillations have been reported in the predictions of pipe-filling bore fronts associated with the transition between open-channel and pressurized flow regimes. These oscillations can compromise the stability of numerical models. A study of these oscillations indicates that the strength of the numerical oscillations is associated with the sharp discontinuities… CONTINUE READING
