The Whirlpool Splitting

An unusual phenomenon called “whirlpool splitting” by analogy with an axe splitting wood logs was experimentally observed. In this experiment, a metal ruler, set vertically on the bottom of the aquarium on the hole axis during flowing out of water has led to the separation of a whirlpool into two formed on both sides of the rule and existed until the end of draining. The paper describes some results of experiments based on the research of this phenomenon
