- W2892448839 abstract "The computational study is conducted to evaluate the low and high subsonic speeds aerodynamic characteristics of the modified airfoil profile. This profile is created using the mean-camber line of the Eppler-197 airfoil profile and the NASA LS-0013 symmetrical profile. The ANSYS FLUENT, a commercial computational fluid dynamic code, is applied to calculate the aerodynamic parameters. At low speed condition, the study is conducted at Reynolds number from 1.5 × 106 to 6.0 × 106 and angle of attack is varied from –4° to 18°. At high speed condition, the Mach number is varied from 0.4 to 0.7 while the Reynolds number is fixed at 9.0 × 106. The range of angle of attack is taken as −2° to 6°. The results indicate that the modified profile has better characteristics than the original profile. At low speed range, the maximum lift coefficient and maximum lift-to-drag ratio are higher than the original profile. However, the minimum drag coefficient is lower. The characteristics of the modified profile at high subsonic speed is also better than the original profile. At Mach number more than 0.64, the lift coefficient and lift-to-drag ratio are also higher while drag coefficient is lower when compared with the original profile." @default.
