Plunging current caused by nonmonotonous water density dependence on temperature
Tóm tắt
The results of laboratory experiments are presented in which a surface jet of fresh water flowed on the inclined bottom of a freshwater tank. The main attention was focused on the plunging of the inflowing water. It is shown that plunging can occur not only in the case when the density of the inflowing water is initially greater than the water density in the tank. Under specific conditions, a jet of water with initially smaller density can also plunge. The necessary condition for this effect is that the water temperatures in the jet and in the tank should be at different sides of the maximum water density temperature.
