Abstract.
This paper presents CFD analysis of the effect of syngas combustion in a full scale gas turbine combustor with specific emphasis given to the flame and flue gas temperature distribution.
The simulation result is validated with the flame temperature of typical natural gas combustion.
In this work, only a single can is considered for CFD model and the schematic diagram illustrating the can combustor is shown inFig.2.
Generation a good mesh is very important in CFD.

CAD model for CFD analysis.
In order to study the effects of the building’s facade redesign on its wind environment the state-of-the-art tool which allows combining quick building modeling with advanced computational fluid dynamic (CFD) simulation has been employed.
Applied CFD interface has been designed to run the simulations with simplified settings where geometry and boundary conditions are upper-set.
Grid independence analysis has been fulfilled by comparison of the CFD simulation results of two different grid spacing values – 2 (for the rest of the calculations) and 3 meters.

Abstract.
Based on the simulation results, discussion is presented in this paper to offer the possibility of better control of the GaN film growth process and to ultimately lead to an optimization of the process.
Previous studies on the temperature in MOCVD reactor chamber focused on the simulations of parameters such as the gas flow in the reactor and the shape of the reactor [5,6].Computational fluid dynamics (CFD) simulation is considered as a significant approach to predict the GaN film growth rate and to examine the dependence on various critical parameters.
CFD simulations, considering gas-phase and surface chemical reactions, were carried out using the commercial software Fluent, based on a finite-volume approach.
Conclusions The CFD has been used to simulate a two dimensional mode of GaN deposition in a vertical MOCVD reactor.
