Sj. Weinstein et al., TIME-DEPENDENT EQUATIONS GOVERNING THE SHAPE OF A 3-DIMENSIONAL LIQUID CURTAIN, Physics of fluids (1994), 10(8), 1998, pp. 1815-1818
In a previous paper, Weinstein et al. derive time-dependent equations
that govern the response of a planar liquid curtain falling under the
influence of gravity and subjected to ambient pressure disturbances. I
n the previous study, disturbances to the curtain are assumed to be tw
o-dimensional, and thus, the curtain response is independent of widthw
ise location in the curtain. In this paper, we generalize the previous
equations to incorporate the widthwise dimension. The validity of the
se equations is demonstrated by their ability to predict standing wave
shapes in agreement with those studied by Lin and Roberts. (C) 1998 A
