Model Arrangements A CFD model developed by the NIST named FDS (Fire Dynamic Simulator) is used here to simulate the smoke movement of in the shafts during a building fire.
The door cracks are assumed to be the gaps of 0.1m width for the convenient of numerical simulation.
In FDS simulations, the shaft is divided into small cells, and the detailed field distributions are obtained, which agree with the real fire scenes.
In the simulation, the pressure value of the orifices of shaft is output, shown in Fig. 4.

But the simulation images of the diffusion disciplinarian are not conveyed by image processing, the studies of two-dimensional fluid diffusion field are researched by digital image processing in this paper.

This present CFD package applies the finite volume method to covert the governing partial differential equations into a system of discrete algebraic equations by discretizing the computational domain into grid mesh.
For a transient simulation, an initial condition is also required to numerically close the equations.
Since the overall error CFD computational is mainly a combination of grid density and convergence criteria.
For this purpose, before verifying our CFD numerical results first we perform a grid study case.

It can be seen that since three dimensional CFD program is adopted in this paper, high temperature layer is formed on the inlet wall for boundary layer effect, and the second and third shock is not clear enough, but the temperature agrees well with the reference[4].

The commercial CFD code FLUENT is used to model the plasma and the solid anode part.
If we want to study the complex external environment (current, cross-flow, external magnetic field etc.), case-by-case should be based on, and a more sophisticated model is needed for numerical simulation.

In 2006, Gao and Rowe [3] discussed the cooling performance of the refrigerator of the electric chip, and searched for the parts of potential improvement by using module simulation.
After the theoretical design and predictive estimation, the simulation test was conducted by using the software of FLUENT.
In the simulation, for consideration of the air convection and heat exchange between the external space and the air-conditioned space, the simulated values are relatively lower.
Coupled with the CFD software for the calculation of the fluid mechanics software, actual and simulation data were compared, confirming that the trends of the actual measurement data and the simulated data are the same.
