Simulation of the MOCVD Reactor for ZnO Growth S.
The simulation results are useful for the practical growth of ZnO.
However, computer simulation has many advantages over experiment method.
In this paper, we utilize a computer-modeling tool, which bases on computational fluid dynamics (CFD) called FLUENT, to solve the various transport equations in the growth process.
In the simulations, the mole fraction remained constant.

In this paper, the distribution of temperature field and velocity field of the multi-temperature refrigerated trucks were simulated by using Computational Fluid Dynamics (CFD) software Fluent.
Numerical simulation of multi-temperature refrigerated trucks Computational Fluid Dynamics is a numerical simulation tool based on computer technology for solving fluid flow and heat transfer problems.
CFD application is related to the heat transfer problems in the process of food frozen, refrigerated and vacuum cooling[7,8,9].
According to the simulation in the cooling zone and the normal temperature zone, this region can better meet the temperature requirements than that in Fig.3(a).
When the air outlet was placed in position B and the wind speed was set as 3m/s, the numerical simulation results for velocity field were obtained and analyzed.
