Swing State Tube Falling Film Flow Of Flow Field Simulation

Ocean fish culture of our country is faced with two serious problems, one is environment pollution and the other is energy waste. It is one of important ways to solve the problems to use absorption system on the ocean fishers. But the change of the performance of the absorber, which is an important component in the absorption machine, under the fluctuant state of the fisher is the key that determines whether the absorption system can be used on ocean fishers. In this paper the flow field of falling film along the inner of vertical tube is simulated and it's the necessary base of the further research that includes characteristics of heat and mass transfer in the absorber under the fluctuant state.In this paper the ocean fisher's movement in the ocean is studied and the physical and the mathematical models of fisher are founded, then the expressions of the force caused by the movement are obtained. The expressions are combined with partial different equations of falling film under the static state, thus the mathematical model of the falling film under fluctuant state can be gained. After simplifying the equations and supposing the profile of velocity, the integral equation of the falling film is gotten. Then the flow field of the falling film can be simulated through dispersing the integral equation and using numerical methods.Comparing the flow field of computation under the fluctuant state with which under static state, the conclusions can be drawn that the fluctuant movement has a very important effect on the movement of falling film.
