Abstract :
In this paper flow field between the first-stage of gas turbine blades, GE F9 model is simulated and analysed using Computational Fluid Dynamics. Two-dimensional model is considered and by applying appropriate boundary conditions for both steady and unsteady state cases are solved. Due to complexity of flow field Reynolds Stress Model is used as a turbulence model. Finally, flow pattern is achieved and shows that pressure in the stationary blades (Nozzles) and the moving blades is reduced and velocity increases in the nozzles and decreases in the blades. It is be noted that complete grid study is done to achieve grid-independent solution.
