Hi Rob, you are correct, if I bounce a bucket of water up and down for a short period of time, then the free surface will stabilize after some initial slopping.
However, if I continuously keep bouncing the bucket up and down, does the free surface stop sloshing?
This was actually an experiment explained in this paper by Chiba et. al. (2016), https://doi.org/10.1016/j.jfluidstructs.2015.11.011
Another paper by Xue et. al. (2019), used the plot from this experiment to validate their numerical model, https://doi.org/10.1016/j.oceaneng.2019.106582
I was attempting to do the same by validating my sloshing numerical model but facing problems.
