This study presents optimal design of wind booster, by utilizing Computational Fluid Dynamics (CFD).
In CFD-based experiments, guiding and throttling effects of the wind booster are able to increase mechanical power of a VAWT.
In this work, a wind booster is proposed for CFD-based analysis and optimization in order to improve angular speed of the VAWTs.
Results and discussion The experiments of VAWT rotations are performed with CFD-based simulations by utilizing XFlowTM CFD software [5].
In simulations, the wind speed is varied from 1 m/s to 8 m/s for low wind speed conditions.

The lattice Boltzmann method (LBM) is relatively novel and contrasts with the usual well-known methods to physical modeling in the domain of computational fluid dynamics (CFD).
Indeed two different matters with special ingredients and ideas are handled when the LBM is considered to physical modeling in the CFD domain instead of the usual numerical methods.
Dimensionless parameters used in the simulation and their characteristic values, calculated for SiGe solution, are predicted from [47].
The present LBE-based model is found numerically more efficient than usual CFD methods under particular situations.

Finally, the unsteady flow field of a reduced order model development trends and application prospect were analyzed, and pointing out that the CFD simulation is still accurately predict the plane stability and handling the most important method.
In addition, the scope of application of reduced-order model is currently mostly other simple shape of the wing subsonic, transonic simulation, simulation of supersonic complex shape to be further developed.
Therefore, CFD method is still accurate prediction of aircraft stability and handling of the most important methods.

Introduction Computational Fluid Dynamics (CFD) is an engineering tool that assists experimentation.
Its scope is not limited to fluid dynamics; CFD could be applied to any process which involves transport phenomena with it.
In CFD a problem is simulated in software and the transport equations associated with the problem is mathematically solved with computer assistance.
The turbulent dynamic viscosity is computed from μt = ρν ∱ν1 (6) K- Model The standard K- model was considered for this simulation.
