Abstract.
CFD Models Basic Equations.
The standard k-e turbulence model is chosen in this simulation because it has been widely validated in dispersion simulations [5,6].
Summary In this study, CFD models for simulating CO2 dispersion over a real terrain are presented.

Recently some attempts to use CFD to
predict inertial separator performance can be found.
Pressure drop of wave-plate separators with different vane spacings under various inlet velocities are gained using CFD simulation method , and the result are shown in Fig.7.We can see that pressure drop increase greatly with the increasing of inlet velocity,and under the same inlet velocity, the separator with large vane spacing has lower pressure drop.
The resistance characteristic is drawed in Fig.9 and compared. with CFD result.
Fig.8 Schematic of experimental apparatus and experimental device Fig.9 Pressure drop of separators as function of inlet velocity (layer spacing is 10mm and 12 mm) Conclusions CFD simulation and experiment method are combined together in this study to predict the pressure drops of a kind of wave-plate inertial gas-liquid separator.
Pressure drops acquired by numerical simulation and model experiment agree well, So the numerical simulation method is reliable in the resistance characteristic research of wave-plate inertial gas-liquid separators.

The CFD numerical simulations consist of two and three-dimensional transient and steady analyses.
CFD Simulations were made find the relationship between the flow rate and the blade geometry.
These results are very similar to the ones obtained in the CFD analysis.

The CFD simulations were made using the software Fluent 6.3.26.
A complete CFD model, taking all these phenomena into consideration, has not yet been attempted.
The cyclone inlet velocity was 10.2 m/s in all simulations.
Three of these escaped after small residence times, indicating a possible short cut between inlet and outlet, due to the low height vortex finder used in this simulation.
Fluent’s built-in boundary conditions were used in this simulation.

CFD simulation and analysis.
However, CFD numerical simulation takes into account variety of conditions.
Hence, the results of CFD numerical simulation are more accurate.
(2) CFD simulation results show that the location of the maximum flow velocity is at each cavity arc.
Moreover, CFD numerical simulation is more credible.

A computational fluid dynamics (CFD) model with k-epsilon turbulence method is a simulation tool for determine the spray characterization.
There are a number of different simulation software that can be used such as ANSYS software, and computational fluid dynamics (CFD) software.
A nozzle was designed by using SolidWork and simulation using ANSYS software.
K-epsilon (k-ϵ) model was chosen for simulation analysis compared to the others model because the analysis results of simulation are more accurate.
