Abstract

The performance of a turbine is very important because it is the yardstick in determining the ability of a turbine to produce the power output. There are various aspects to assess when determining the performance of a turbine. However, aspects that will have a big impact on the performance of the turbine are the turbine blade profile. There is various type of blade profile we can found which have different in their dimension such as the thickness, deviation angle, incidence angle and others. The profile categorized in code name called National Advisory Committee for Aeronautics (NACA). These different profiles will produce difference performance level in their work. In order to find which profile blade can produce the higher performance during operation, an analysis on the profile need to be done. The analysis can be carry out by doing computer simulation software call ANYSYS CFD Fluent on the blade. Result from the analysis can use to determine which profile blades have better performance. The analysis conduct on 2-dimension single blade, which will five different profile at same 15-degree angle of attack and same 400 m/s velocity. The selected profile is NACA TN3802, TN 5508, TN 6508, TN 2202, and TN6408. From the simulation, the results that can obtained are pressure and velocity distribution around the blade and the lift and drag acting on the blade. The result obtain can be used to analyze which profile blade is better. Based on the pressure different result, NACA TN 6508 has the highest value at 185723.7 Pa and it has lift to drag ratio at 6.7851, which also the highest among the five profiles selected. The assessment for this analysis more focusing on the lift to drag ratio of the blade. As the result, NACA TN 6508 is chosen as the best blade profile compared to the other four selected blade.
