This is done using Computational Fluid Dynamics (CFD) simulation where the aerodynamic performance a wing derived from a natural bat wing shape was studied.
The objective of this study is to study the aerodynamic performance of a flapping wing derived from a bat wing using a Computational Fluid Dynamics (CFD) simulation.

Abstract.
The CFD analysis provides three-dimensional view of thermal and gas flow field inside the thermal oxidizer chamber.
The performance of this method is demonstrated and discussed based on the results of the test simulations.
Field tests (not reported here) indicate excess CO emissions therefore prompted to undertake CFD simulation to troubleshoot oxidizer the observed problem.
The CFD results provided guidelines to redesign the old oxidizer resulting into better performance.

Abstract.
The method of the computational fluid dynamics (CFD) is to adapt to this trend and is developing into a new design tool.
Simulation Results The macroscopic flow field.
Although the method of CFD can not be completely replaced by the experimental method at this stage, you can analyze and display the phenomenon occurred in the flow field through the CFD software.

In this panorama, the current academic-industrial trend is determining numerical (simulation) of constant “C” through a methodology which is based on Computational Fluid Dynamics (CFD) techniques, in order to remedy the experimental dependence on the calibration or operation of these flow meters.
In this article, numerical simulations are performed through the commercial code Fluent.
The experimental data and fluid dynamics simulation are shown in Fig. 2.
Characteristic Curve of Orifice Meter (CFD) and experimental data from [4].
Another important tool provided by CFD techniques consists of certain variable calculation along a given boundary.

Thirdly, the fluid structure interaction simulation model is simplified to the structure simulation model, by adopting shell 181 element and using a pressure acting on the workpiece directly instead of the CFD model.
Some simulations about the forming process are given in section 3, including fluid structure interaction simulation and structure simulation.
Then, about WJ, we use a pressure acting on the workpiece directly instead of the CFD model.
WJ was modeled and simulated with a CFD approach, while for the material flow in the workpiece a FEA was used.

The numerical optimization method was used to analyze the influence of combined variation of two angles on the external flow field and the CD of the passenger car, in which we combined genetic algorithm with the CFD simulation to reduce aerodynamic drag by seeking the relatively optimal combination of two parameters above.
With CFD method we can acquire the diagrams of total pressure and streamline distribution in the flow fields of the models which has been proved to be reliable because of the mature development of simulation of flow field around automobile and pipeline flow.
CFD numerical simulation was applied to get the CD and the diagrams of total pressure and streamline distribution in the flow fields of the MIRA model of 10 angles combinations.
