By the way of Computational Fluid Dynamic (CFD), Sun et al. find that it was added mass effect provided the extra force at the beginning of each stroke[3; 5].
By the way of CFD, added mass force can be calculated, however, it will take days or even months to get a result, and a man made insect inspired MAV can’t wait such a long time to get a result to be used in real time feedback control method, this makes CFD method impractical in calculating added mass forces during MAV’s flight.
Simulation Results Insects might adopt a lot of possible wing kinematics[15], however, Sane & Dickinson found that the simplest stroke plane “－” is very efficient in aerodynamic force generating[15].
Simulations were carried out in MATLAB.

2D Simulation Flue Implementing the Lattice-Boltzmann method.
Currently in the process of engineering, but increasingly implemented simulation methods since they are an economical and feasible to predict the behavior of some variable you wish to benefit.
For engineering there has been widely implemented the methods of CFD (Computational Fluid Dynamics), in which the you hand a solution for the Navier-stokes equation applying conditions of Diriclet, Newman or Robin [3] This article will study other frontier conditions in terms of transmission functions of the method, given an interest on studying convective flows [4], which are vital because they appear in infinity of situations in both engineering and science.

Fig. 5 Comparison of axial force coefficient X on the generic bare hull Fig. 6 Comparison normal force coefficient Z′ on the generic bare hull In this part, a 2D in house code-CADMV and commercial CFD code FLUENT are introduced for simulation of the flow field and hydrodynamics for SUBOFF model.

Introduction FLUENT is world's largest computational fluid dynamics (CFD) software vendor and technology service provider.
This software is designed based on the idea of FLUENT CFD software group.
However, due to the limitations of such simulation software and the complexity of the geometry of the wall heat transfer problems, the simulation results of this study need to be further validated [3].
During the simulation, thermal conductivity has used different constant values.
Steady numerical simulation is conducted by FLUENT software.

By comparison between the simulation results and the corresponding wind tunnel test data, The results indicated the simulation result of RNG k-εturbulence model is more precision, and it is more suitable on numerical simulation in vehicle external flow field.
At present, the numerical simulation of turbulence flow includes direct numerical simulation and non-direct numerical simulation.
Depends on the different of simplified foundations, N-DNS include Large eddy simulation (LES), stat average numerical simulation and Renault average numerical simulation (RANS).
