| Abstract: | In order to study the influence of submersible mixer horizontal installation angle on flow field of stirred tank, the different levels of installation angle are established. Through the Fluent threedimensional data of fluid flow in stirred tank with submersible mixers simulation distributions of different schemes of speed are obtained. Using the UDF module the effective mixing volume of fluid and the percentage of the whole flow volume are respectively calculated in the flow field and its velocity reaching to the mixing effect. By comparison, the optimal installation scheme of submersible mixer finally is selected, and a new method for evaluating the effectiveness of submersible agitator and the quality of installation layout is put forward, which is called the effective mixing domain method. |
