Numerical Simulation of A Ceramic Furnace Burner.
Faced with the complexity of the problem and industrial configurations, the use of CFD (Computational Fluid Dynamics) becomes essential to answer many questions.
Sebastian [5] has characterized the flameless combustion of natural gas experimentally and by CFD modeling with FLUENT.
Solution of transport equations is achieved using the commercial CFD software FLUENT version 6.2.16 [11] using its built-in sub models and algorithms.
The simulations included coupled models of turbulence, combustion and radiation.

Applying computational fluid dynamics method (CFD), we can take numerical simulation for the flow around the propeller.
On the other hand, the hydrodynamic performance of the propeller is calculated based on ANSYS ICEM CFD software, which is a powerful pre-processing software and it can provide high quality meshes for the mainstream CFD software(FLUENT CFX etc), making the result more accurately[4].

After the validating the feasibility on methods, the mixture preparation of a LPG center injection DISI engine is studied using common CFD software (FIRE v2009).
It should be pointed out that there is no LPG property database (60%propane and 40%n-butane) in former CFD software FIRE v2009.
Fig. 3(b) shows the CFD estimation results, in which the rich cloud position and the fuel mass fraction are in close agreement with the experiment result.

Researcher could resolve it by adopting the latest Computer Fluid Design (CFD) airbag simulation technique which have a better simulation result of OOP load, since CFD method provide more realistic airbag deployment simulations especially in the first few milliseconds which are significant in OOP test.
Ruff et al. [28] and Haufe et al. [29] also agreed that CFD did provide more realistic airbag deployment simulations especially in the first few milliseconds which are significant in OOP test.
However, it may need more effort in setting up the simulation model.
Recently, Potula et al. [32] using CFD simulation method, called smooth particle hydrodynamics (SPH) in LS-Dyna to evaluate the safety of occupant when side curtain airbag deployed either occupant is in-position or OOP.
By adopting latest CFD airbag simulation methodology, simulation result of OOP load case are more accurate, since CFD method provide more realistic airbag deployment simulations especially in the first few milliseconds which are significant in OOP test.

In this paper, we will provide a summary of general purpose computation of GPU, including graphic pipeline, the history of GPU architecture evolution, software environment, as well as the CFD applications on GPU.
The area known as Computational Fluid Dynamics (CFD) is one of the most prominent areas in scientific computing.
Because of the high computational requirement of solving N-S equations, researchers tried to map vary of CFD solvers to GPU.
By examining single- and multi-GPU lattice-Boltzmann simulations with ANOVA, they showed that all the lattice-Boltzmann simulations primarily depend on effects corresponding to simulation geometry and decomposition, and not on the architectural aspects of GPU.
In this paper, we provide a summary the GPU computing in CFD applications to guild the development CFD applications on GPU.
