The article designed a water model in axially rotating cylinder and built up an experimental platform. The equipment was put into a refrigerator, and as time went by, the temperature of environment changed regularly and the same is the rotating water. Based on this, different temperatures in different positions and the change of temperature were measured. Besides, comparing with the general water, heat conduction equation was obtained, and the reason of such phenomenon was analyzed. Simulating based on practical condition, the results by theoretic analysis were good matched with experiment. At last, it gave some reference values both on theoretical and experimental aspect for industry application. [ABSTRACT FROM AUTHOR]

We analyzed the phenomenon which is similar to "node" and " serratula" generated by natural pouring water, restored the phenomenon through a large number of repeated experiment and figure out the causes of the phenomenon with the combination of mechanical analytic modeling and computer simulation. This paper, by using the fluid continuity equation, combined with the appropriate boundary conditions, obtained the exports rate distribution of water in the smooth cylinder, and pointed out that the functional relationship between the node and quantity of flow. We manufactured asymmetric rate distribution to produce rotation of the water column. Finally, through simulation, we improved the credibility of the theory. [ABSTRACT FROM AUTHOR]
