By means of ANSYS, piston finite element model is constructed to attain transient numerical simulation and explore the characteristics of surface temperature.
Finite element numerical simulation technology has gradually becomes the important means for research on engine performance by virtue of its unparalleled advantages over test methods and theoretical analysis [1].
In the simulation calculation, the original empirical formulas have to be modified in accordance with different models.
Thus it may be considered to combine CFD and finite element to find the solution.
At the same time the simulation experiment is conducted by means of finite element model established by Ansys. 　

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.

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.

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].

The use of the three-dimensional environment CFD allows us to combine the pyrolysis model with the combustion model in the gas phase and the thermal radiation model for the simulation of the fire development in a small building.
The simulation data show that the model is able to predict the early “inflammation” and “after-the-inflammation” behavior inside the building.
These studies are not only an attempt to combine the simulation of the solid and gaseous phases for construction materials but these are also the platform for the simulation of the fire development at the time of the combustion of the solid flammable materials.
