چکیده
The objective of this study was to optimize the design injection nozzle hole fuel injector a model MGT engine. To achieve higher combustion efficiency mixed gas in chamber, first, well-mixed homogeneous should be formed accelerate flame propagation chamber reach temperature and pressure. In study, four different shapes were designed, formation characteristics numerically analyzed. Three parameters—the penetration, diffusivity, amount injected—were analyzed compared find optimum shape with highest chamber. CFD analysis conducted using general-purpose (Computational Fluid Dynamics) code-named PHOENICS (ver. 2020). Based on results, it found that penetration length (lp), diffusion angle (θ), volume flow rate (Q˙f) injected Model 3 had best for condition Especially, 3, which directly affects output power engine, increased by more than 5%. This result is useful informative making sample combustor performance test turbine

Combustion of Reformed Gas and Liquid Fuel in Crgt Combustor
Original scientific paper Numerical simulations of four combustion processes in a dual-fuel combustor of chemically recuperated gas turbine (CRGT) were carried out in this work. The fuels in the four combustion processes were liquid fuel, liquid fuel + steam, liquid fuel + reformed gas and reformed gas, respectively. The mathematical models adopted for different fuels combustion consist of real...
