.... Nevertheless, limits of Lax shocks, when one of the inequalities become an equality, occur in multiphase flow, even in the Buckley-Leverett case. By allowing Lax limits, wave groups form. Each wave group is a consecutive sequence of a rarefaction wave and a shock wave or vice versa. Consecutive waves...
