For simulation of wind flow is used OpenFOAM software with k-epsilon model, which is in many papers represents as one of the best and most reasonable model for evaluation pedestrian comfort.
With CFD can be evaluate this problem very effective and not even time-consuming compared to wind tunnel experiment.
For calculations is used OpenFOAM, which is free, open CFD software.
CFD and turbulent flow Turbulence is the state of fluid motion that is characterized by apparently random and chaotic tree-dimensional vorticity.

2D CFD Analysis of Micro Arc-groove on the Surface of Tribopairs P.Y.
And then CFD is selected and accepted gradually to be a timely way to study complicated lubrication problems.
In addition, the "engine oil" and "steel" in CFD codes are defined as fluid and wall materials in calculation models, separately.
The surfaces throughout the simulations were assumed to be rigid.
Numerical simulation results and validation experiments are compared, and some conclusions of qualitative evaluation can be drawn to non-smooth application of lubrication problem.

More and more researchers try to port the computational fluid dynamics (CFD) simulations into heterogeneous computers.
With this programming model, we implement a high-order CFD program on “Tianhe-1A” supercomputer system.
As such, researchers accelerated CFD applications in heterogeneous environment and achieved significant speedups.
In CFD solver, the solution is computed iteratively from the initial input data, until a stopping criterion is satisfied.

Based on the fast process of acid-base neutralization, the effects of geometric parameters such as the angle of diffuser, ratio of nozzle diameter to mixing chamber diameter and the position of nozzle on mixing and reaction characteristics were analyzed using CFD in detail.
The velocity is constant in all the simulations at different geometric parameters; At the outlet, the boundary is the pressure boundary.
At first, the simulations are based on various m by varying the mixing chamber diameter with other geometric sizes constant ( m=0.55, 0.45, 0.35 and 0.25).
In the numerical simulations the diffuser anglewere set 0°, 3°, 8°, and 14°, respectively.
