Bubble Formation In The Mechanical Mechanism And Bubble Generator Device

Bubble flotation is a fleetly developmental flotation technique in this years.The amount and size of the bubble is the important influence of the flotation purpose. And the generation of the bubble is a application about the two-phase flow of gas and liquid.The selection about this article come from the natural science fund in YunNan province.The article firstly introducs the historical view of column flotation development and the class of the bubble generation equipment.Then it introduces the flow trait about the air and liquid two-phase flow and the flow chart based on the theory.Secondly it introduces the hydrokinetics governing equation about the numerical simulation and gives the ecumenic form of the governing equation. And take the Monte Carlo method to describe the bubble flowing in the level pipe.The emphases of the article is the self-suction bubble generation equipment designing. And it confirms the affecting factor about the amount and size of the bubble by experimentation.It proves that the bubble generation equipment we desighed is comparative succeed according to the experimental result.In the article we applies the large CFD's business software FLUENT to simulate two-phase flow about gas and liquid in the air bubble happen appliance we designed and ameliorates the configuration about the appliance based the simulated result.The article have some meaning of the research about the selecting mine equipment in Yunnan province.
