This paper mainly makes comparative analysis on four main types of blade in stirred bioreactor by Computational Fluid Dynamics(CFD) simulation.
Now, the bioreactor is often research mainly by experiment and Computational Fluid Dynamics(short for CFD)simulation, and CFD method is becoming more and more popular for its low cost and high efficiency[4].
This paper first build CFD simulation model fit for stirred bioreactor, then simulate bioreactor flow field and optimize the type and structural parameters of agitator blade with Fluent.6.3.26.
No matter stable state simulation or transient simulation, the bioreactor flow field(Fig. 2) is divided into rotation area including impeller(Fig. 2a) and static area(Fig. 2b).
The simulation result is showed in Fig. 8, Fig. 9 and Table. 3.

The "CFD" is used to determine the pressure, temperature and velocity fields in the lubricant film, the stress intensity and displacement field is obtained by "FSI" simulation.
Thus, a parametric study on the one hand it makes the calculation of the fields of pressure and temperature in the lubricant film "CFD".
Using one hand, the numerical simulation Computational Fluid Dynamics "CFD", this allowed us to determine the pressure field and temperature in the lubricant film.
