Introduction

The combustion chamber, or combustion chamber, is one of the key components in the gas turbine system. Its function is as a place for combustion, where the air compressed by the compressor is mixed with fuel. This process produces combustion gases that have high temperatures and pressure. To understand how temperatures and pressures are distributed in the combustion chamber, as well as to identify critical areas, simulation is carried out using Ansys CFD (Computational Fluid Dynamics) software. Computational Fluid Dynamics (CFD) is a powerful tool that enables engineers to analyze and predict fluid flow, heat transfer, and mass transport phenomena in various engineering applications. In this study, we will focus on the analysis of temperature and pressure distribution in the combustion chamber of the Siemens V 94.2 gas turbine using Ansys 15.0.

Design and Simulation Methodology

The combustion chamber design is carried out using Solidworks 2011 software. The parameters used in the simulation include compression air temperatures of 722 K and 8.5 bar pressure, and natural gas fuel (CH4) with an entry speed of 20 m/s and an initial temperature of 300 K. Through this simulation, the resulting data is obtained after iteration 100 times. The data includes temperature, pressure, and air flow velocity. CFD simulation is a complex process that requires careful consideration of various parameters, including geometry, boundary conditions, and material properties. In this study, we will discuss the methodology used to design and simulate the combustion chamber.

Distribution of Temperature, Pressure, and Velocity of Air Flow

In this study, the analysis of the distribution of temperature, pressure, and velocity of air flow was carried out in three fields: XY, YZ, and XZ. The simulation data is then converted into graphics to provide a clear visualization of changes in parameters in the combustion chamber. The results of the analysis show that the highest temperature, pressure, and flow velocity is found at the position of position 5 <7 m. This position is located right in the middle of the combustion chamber and visually is a critical area that needs attention. Visualization of simulation results is an essential step in understanding the behavior of complex systems. In this study, we will discuss the visualization of temperature, pressure, and velocity of air flow in the combustion chamber.

Analysis of Results and Implications

The results of this simulation provide important insight into flow behavior and combustion conditions in the gas turbine combustion chamber. By knowing the distribution of temperatures and pressures, as well as flow speed, engineers and technicians can optimize design to improve turbine efficiency and performance. For example, by analyzing critical areas that have the highest temperature and pressure, efforts can be made to prevent damage due to excessive heat or extreme pressure. In addition, this data can also be used in the development of materials that are more resistant to extreme conditions in the combustion chamber. Optimization of design is a critical step in improving the performance of gas turbines. In this study, we will discuss the implications of the simulation results on the design of the combustion chamber.

Conclusion

Simulation analysis using Ansys 15.0 provides a clear picture of the temperature and pressure distribution in the combustion chamber of the Siemens V 94.2 gas turbine. These results not only show the position of critical areas, but also open up opportunities for more efficient technological development. At the same time, this research becomes important in ensuring the safety and sustainability of the gas turbine operational, which is one of the main sources of energy in this modern era. By understanding and applying the results of this simulation, we can continue to innovate in a better and efficient design for the combustion system in the gas turbine.
