This paper tries to simulate a numerical wave tank by FLUENT CFD software using k-ω turbulence model in a two-dimensional domain.
The simulations show that the amplitude of the transient wave decreases while the relative breadth increases.
Here, the numerical wave tank is simulated by FLUENT CFD software in a two-dimensional domain.
The simulations show that the amplitude of transition wave decreases with the relative length increase.
Then this time step is chosen for next numerical wave tank simulation.

Based on the theory of fluid dynamics, this study uses CFD software Fluent 6.3.26 to conduct numerical simulation of the models in wind tunnel tests by Yong Chul Kim involving four working conditions of different spacing or area density in regular arrangement.
On the contrary,numerical simulation has the advantages of low cost and easy operating,etc.
Scholars in late 1980s researched wind tunnel testing and numerical simulation of wind field and environment of building culsters.
Numerical Simulation Numerical simulation adopts professional CFD software platform Fluent 6.3.26 and it is based on the steady-state Reynolds averaged N-S equation and uses turbulent enclosure model and turbulent diffusion to seek out solutions.

In this paper, the numerical wind tunnel method (NWTM), based on the Computational Fluid Dynamics (CFD), is applied to study wind load.
Reliability of numerical wind tunnel method To verify the reliability of the NWTM, a CFD simulation was carried out with the full-scale model under the same conditions as those of the wind tunnel experiment.
The boundary conditions of the CFD simulation were also set identical to those of the wind tunnel experiment.
Conclusions The present CFD predictions have been found in fair agreement with WTT, a fact indicating the validity of the present model despite the different formulations.
