Master Thesis Report Verification of 2D Fitting Results The results in table 5.9 suggests that the surface fitted profile of 1865 and 1265 are shaped differently from their respective 2d fitted and actual point counterparts. This was a similar conclusion reached when a comparison of profile 1865 and 1265 blade loadings and Mach/Pressure contour were made earlier. As for profile 1565, the results of the stagnation pressure loss coefficient reveal that the Actual point profiles are shaped differently from its respective 2d fitted and surface fitted counterparts. This is in line with the results concluded from the blade loading plot and Mach/Pressure contour of profile 1565. For these results, it was also found that the 2d fitted and surface fitted profile have the closest fit. As for profile 2265, the results of the stagnation pressure loss coefficient reveal that the surface fitted profile is shaped closely to the 2d fitted profile. This was a similar conclusion reached when a comparison of profile 2265 blade loadings and Mach/Pressure contour were made earlier. When the simulations were carried out for the various 2d blade profiles, it was found that profile 2265 behaves more like a turbine instead of a compressor since the static pressure increases across the blade profile. Therefore, an investigation was carried out to understand this physical phenomenon by looking into the area distribution across the blade profile. An illustration of the respective area distribution belonging to the different blade profiles is shown in figure 5.58. 0.04 0.038 0.036 0.034 0.032 0.03 0.028 0.026 0.024 Plot of Blade to Blade Area Distribution D6 Ar Dist 6 Area Dist Area Dist Ar ea ea ist 1265 1565 18 22 5 5 The start of the Kink signifies the star t of the outlet region 0 0.2 0.4 0.6 0.8 1 x Figure 5.58: Area Distribution for various blade profiles In figure 5.58, it should be pointed out that the step change in area distribution (or start of a kink) for the various blade profiles represents the beginning of the outlet region for the blade to blade domain. Firstly, it can be seen that the actual blade to blade domain becomes smaller with increasing stagger angle. Secondly, the total change in area distribution also becomes smaller for blade profiles located closer to the tip than the hub. Thirdly, it can be seen that profile 2265 exhibits the smallest change in area distribution within its blade to blade region. Therefore, it is possible that profile 2265 behaves more like a turbine instead of a compressor since the flow converges for about half of the total blade channel before it diverges. The resulting effect would still be an increase in the velocity despite the flow diverging for a small section of the blade channel. 62 yPDF Image | Aerodynamic Design of the NASA Rotor 67 for Non Uniform Inflow
