Abstract

The need for energy is a fundamental thing needed in an effort to improve people's lives. As the standard of living and quantity of the community increases, so does the need for energy. At this time energy needs are directly related to the level of community life and industrial progress in a country. In this case, electrical energy is one of the most widely used forms of energy in society, because electrical energy can be easily and efficiently converted to other forms of energy. In general, steam power installations are known as Steam Power Plants (PLTU), which at this time are still an option in the conversion of power from small to large scale using conventional fuels or biomass into power in meeting electrical energy needs. In this power plant, the primary energy that is converted into electrical energy is fuel. The method used in this study is a simulation analysis method. In general, the methodology used in this study is divided into two stages, namely: Geometry modeling by inputting airfoil coordinates with 2014 solidwork software and airfoil model simulation using flow simulation that has been integrated in the 2014 solidworks software. The type of airfoil that is simulated in this study is NACA 0012 modification with inlet fluid pressure of 0.1013250 Mpa and temperature of 350 ℃. Where aerodynamic parameters used in this study are the amount of pressure that occurs around the airfoil, and the forces that occur on the airfoil caused by changes in the angle of attack and angle of the fin. Speed and pressure are the aerodynamic parameters used in this study. From the simulation results it can be seen from the contour of the NACA 0012 airfoil pressure distribution used on the steam turbine blade. From the analysis of simulation data, the following conclusions are obtained: The largest number and inhibitory coefficients occur at the same time, when the airfoil is at an angle of attack 〖15〗 ^ 0 and fin angle 〖20〗 ^ 0 that is equal to c_L = 1.317717571 and c⁄D = 0.329545209. While the smallest lift and inhibitory coefficient occurs when the airfoil position is at the angle of attack 0 ^ (0) and the angle of the fin 0 ^ 0 is equal to c_L = 0.0253938546 and c_D = 0.02491205 and at the simulation the stall condition occurs at the angle of attack The airfoil is between 〖15〗 ^ 0 and 〖20〗 ^ 0. As for the suggestions given in subsequent studies, namely: More mastering the CFD so that it can do the maximum testing, More variations in the angle of attack and angle of the wing fins during the simulation, and do the simulation to get the stall conditions on the aircraft wing airfoil. Keywords: Steam Turbines, CFD
