Abstract: In this paper, taking a building in Wuhan as a case, the CFD method is used to simulate the air flow field and temperature field of respiration double-skin facade,and by analysis, we know how the position and size of air inlet and air outlet can influence the thermal performance , and their area ratio2:3 is suggested with staggered arrangement.
Meanwhile, according to the simulation results of the three models, we come to the conclusion that the special structures of double-skin facade can form natural convection heat transfer, take away the heat in channels and achieve the goal of energy conservation and consumption reduction.
Computation model and boundary condition This paper presents the numerical simulation of double-skin facade by using PHOENICS3.6.2 and the HVAC special module of FLAIR.
By numerical simulation, we can obtain useful conclusions on whether the upper vent should be larger or the lower should be larger.

Abstract.
A simulation model of the gas-solid flow in a 120 m3-oxygen blast furnace by using a DEM-CFD coupling module[2] applied the DEM and CFD to set many particles in a granular system, and the additional effect of the void fraction on the gas phase, respectively.
At the begining of the relative simulation time (t/ts) at 0.33, the hot metal and slag droplets started to drop and flow down from the inlet zone to the coke bed.

Quantitatively, the differences between experiment and CFD with respect to the velocity profile are acceptable.
Before presenting any result, a preliminary experimental test is compared to a CFD code (MaPFlow).
A brief introduction to MaPflow Eulerian CFD is by far the most popular simulation method in aerodynamics.
This is because the CFD and experimental data have similar velocity profile in the wake.
However, if we compare the deficit area only, the differences are not negligible (around 20%) The reason is that even though we have taken measures (honeycombs and screens) to reduce the flow turbulence for the wind tunnel experiment, essentially the flow are still not uniform while in the CFD simulation, the flow can be set to be uniform.

Abstract.
Based on Hydromechanics, the relational mathematical models of catalytic converter simulation are established and the parameters are calculated.
Making use of CFD numerical simulation method, a simulation is set up for the internal flow field of catalytic converter original model using fluent software.
From the simulation, the internal flow characteristic is understood.
Such as Lai et al applied PHOENICS software to establish a 3D model without chemical reaction and adiabatic and 3D numerical simulation of steady state flow was made to catalytic converter [3].

CFD, as a powerful analysis technique develops very well.
The simulated results predicted by CFD model are consistent with experimental data.
CFD simulation model of milling cutters with different internal channels The present research selected three milling cutters with different interior channels, i.e., single direct hole, double direct holes and double helical holes.
Hence, cold air is used instead of Cryogenic oil mist in this CFD model.
So the velocity field of the CFD simulation model is available.
