The flowing liquid chooses the configuration that maximizes its access, i.e. the architecture that allows it to flow the easiest and come to rest the fastest. The choice between round splats and splashing is dictated by the new dimensionless group G, which physically means a ratio of two length scales...", An article from A. Bejan and D.
