After modeling 3D beam structure by using ANSYS Design Modeler, structural analysis for the given load was performed by ANSYS Design Simulation.

Abstract A numerical simulation of the effect of rotation on mixed convection laminar flow with separation and reattachment length is studied.
A planar mixing layer and a planar wake flow subjected to rigid body rotation were simulated using direct and large eddy simulations performed by Metais et al. (1995).
The two-dimensionalization impact of cyclonic rotation and rapid anti-cyclonic rotation was confirmed by their simulations [4].
Numerical simulations.

SOLIDWORKS and MATLAB simulation software were used for the design of the Train Roof-Tops Wind Energy Conversion System (TRT-WECS).
The former was used to perform computational fluid dynamics (CFD) on the both normal train as well as the train having a turbine installed on the top, and a comparison has been made in terms of various parameters that affect the performance of the newly designed TRT-WECS.
Section 5 is devoted to the interpretation of the simulation results and discussion.
To this end, computational Fluid dynamics (CFD) simulation studies have been conducted to enhance the performance and efficiency of the Savonius wind turbine without affecting the rotor's basic construction.

All simulations were run in 64 bit double precision using a second-order upwinding discretization scheme for all equations.
Simulations were run across 64 processes on the UNSW Trentino cluster.
The walls for all simulations were modelled as slip, zero-shear walls.

This result is similar with the CFD simulation conducted by Jonathan [8].

Also it is figured out that the third (w=2.0D and d=0.75D) and fourth (w=3.0D and d=0.75D) case were more effective than other cases and baseline case and it means the trench depth of 0.75D was the optimum one as well as approved by CFD studies.

(3) (4) CFD software Fluent was employed to solve the partial differential equations.
Grid independency study has been carried before simulation.

For instance, using a computer simulation technique as CFD powered by ANSYS-Fluent etc.

Fig. 1 Physical model Fig.2 Top view of computational flow-fields Numerical model and boundary conditions The commercial CFD code, FLUENT, which is based on the finite volume methods, solves the Reynolds-averaged Navier–Stokes equations for an incompressible fluid and the effect of turbulence on the flow-field is included in the application of the RNG-k-e turbulence model, and the boundary conditions is similar to [4] RECIRCULATION AND DEFINITION Mechanism that the recirculation occurs Zhao Wanli carried out the experiments on direct air-cooled condenser in low velocity wind tunnel, and discussed the mechanism of recirculation occurs [2] Definition of Recirculation Ratio In practice, recirculation is often formed under the action of environment wind.
