Linear analytical solution oto the 2D free sloshing water surface elevation

Hi, all
Does anyone know about the linear (the simplest) analytical solution to free sloshing water surface elevation? Many people have simulated free sloshing water problem as a validation for free surface modeling. As far as I know, the inviscid flow free sloshing in a 2D still rectangle tank is the simplest case. The motion can be approximated by the linear wave theory. And the solution expression can be pretty simple. With free surface starting from a constant slope as initial BC, I found from some paper the following equation: in which and L is the tank length, h is the still water depth and is the initial free surface slope. I wonder if the above expression has kind of typo or missing something, as it introduces some obvious wiggles when I plotted it, which should not appear in a li near solution. So can anyone point out if this is a correct expre ssion? If not, where is wrong? Where can I find a correct one? Thank you. |
