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.

The CFD analysis model was established by adopting the computational fluid dynamics (CFD) method to implement dynamic simulation analysis on air hot in the drying mechanism.
The Reynolds number of hot air inside the air nozzles is 7458099, larger than the critical Reynolds number 13800, so it is turbulent flow and the turbulent flow κ-ε model should be used for simulation calculation.
Analysis was carried out flow characteristics of hot air in air nozzles by adopting the CFD simulation technique and structure optimization was carried out on the air nozzles.

CFD has advantages of changing the simulation condition easily and saving the time and money for experiments compared to the traditional experiment.
CFD has been used in the simulation of the cold store[3], however, there is no literature about studying the effect of setting gap between different products on the air flow distribution.

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.

Fluent is one of the comercial CFD softwares used widely.
It is common that CFD simulation results and the building regulations are combined to assess the built wind environment.
