Stimulation Analyses With application of computational fluid dynamics (CFD) software Fluent [10], the flow pattern of natural gas transporting in the pipeline has been simulated before and after DRA injected, with purpose of revealing the gas flow pattern’s improvement law of DRA acted on the internal wall of pipeline.
FLUNENT: Computer Simulation of Fluid Engineering and Application Examples[M].

With the help of numerical simulations can be nowadays flows represent very detailed and accurate.
Due to the strongly three dimensional and unsteady turbulent characteristics of flow, which are marked with vortex shedding, flow reattachment and recirculation bubbles, the CFD reaches its limits.

Because CFD (Computational Fluid Dynamics) embraces the advantages of visualization and economy, it has become the main method to study the dispersion routes of indoor particles.
However, nearly all experimental validations for computational simulation choose gaseous pollutants or dust particles as research objects, while pertinent bio-aerosols are hardly used.

Along some FSI simulation performed for the reference design shown in Fig. 5 it has been shown, that even for wings with a small span the deflection as shown in Fig. 7 (left) can be remarkable.
Numeric validation performed has been based on a major simulation environment consisting of CAD, CFD and FE software.
Simulations were performed for a variety of flight conditions and parameters.

Program is somehow an inter-stage between simple calculations on the basis of empirical relations and modern simulation methods on the basis of CFD.

Indeed, since the advent of Computational Fluid Dynamics (CFD) and the initiation of experimental work utilizing modern experimental tools, research on backward-facing steps (BFS) has gained significant momentum.
Brés and Colonius [47] performed direct numerical simulations to analyze three-dimensional instabilities in compressible flow over open cavities.
In the present simulations, the Prandtl number is set at Pr = 0.71, corresponding to air flow, while the Reynolds number is set at Re = 200.
