Abstract:

The project is aimed at describing the mixing phenomena of the new reactor. The solide catalyst deposit on the surface of tubes which affect the flux of the reaction product liquid. The liquid scouring effect is necessary which is relate to the velocity of surface tubes. The new design structure i.e.solide catalyst and liquid in a stirred reactor has been simulated using computational fluid dynamics model (CFD). The arrangement of tubes creat a great effect on the behavior of the fluid, especially the veclocity of surface of tubes. The tank with draft dubes or not have obvious different on the power cosumption and the distribution of solid particles. Power consumption is also taken into account. Compared with Japonic reactor, the design reactor is energy saving which have good potential development.
