NUMERICAL ANALYSIS OF AERODYNAMIC PERFORMANCE FOR INVERSE TAPERED BLADES

Abstract

We are aiming to analyze Inverse tapered blade that produced by inverting the chord length at blade tip and blade root and Taper blade based on CLARK-Y airfoil; by running test in wind tunnel at 13 m/s wind speed. Simulate both of them with ANSYS Fluent software with different Reynold’s numbers relatively with different angle of attacks started with (-15) degrees and ended up with (20) degrees. Finally, using the simulation results in Q-blade software with the Blade Element Methods (BEM) to produce Cp - λ curves. The other aim is to understand the physics of the inversed tapered blade.
