Abstract
The use of gas turbines for electrical power generation represents an important fraction in the Brazilian energy matrix and shows a trend to grow in the next years. That justifies the importance of knowing how this equipment works, in order to increase the production efficiency, reduce operating costs and minimize the pollutant emissions. Therefore, this article proposes the use of CFD simulation to study the operation of a gas turbine combustion chamber, since this component is directly related to the efficiency of the fuel consumption process. In order to perform the simulation, the software STAR-CCM+ R was applied, using models of combustion and emissions available in the software. During the simulation, the flow, temperature, pressure and mass flow profiles in the combustion chamber were evaluated, and theresults were compared with the operating parameters of an actual gas turbine used for electric energy generation. From this comparison, it was observed that the flow, pressure and temperature profiles corresponded to reality, which allowed the validation of the used models.
