Overview

This analysis compares a free-wake vortex model and experimental data in a scaled X-Rotor, suggesting the benefit of 3D aerodynamic tools in capturing wake features.

Key Points

CACTUS accurately predicts the flowfield in the rotor volume and very near wake without pitch offsets, and deviations arise with offsets.
Experimental validation reveals that significant differences occur when pitch offsets are applied, necessitating model adjustments for accurate results.
The study integrates 3D aerodynamic aspects induced by coned blades, highlighting their impact on wake behavior compared to traditional 2D models.
Results emphasize the importance of advanced modeling techniques in understanding complex aerodynamics associated with VAWTs.
