摘要
Flows in which a low density (gaseous) phase contributes to the motion of a free surface have been studied numerically using boundary element methods. A stable, time-accurate integration scheme for the coupled, nonlinear free surface boundary conditions is described for the case where both phases are incompressible and inviscid. The effect of increasing the gas/liquid density ratio on the stability of the methodology is briefly discussed. The technique is illustrated through a series of examples involving: an infinite-length (periodic) liquid jet in a 'wind-induced' flow regime; a two-dimensional liquid column subjected to acoustic excitation; and a finite-length liquid jet injected into a quiescent gas.
