Cable construction affects lateral forces and wakes of helically stranded cables under oblique inflow
Cable construction effects on the lateral forces and wakes of helically stranded cables under oblique inflow
Large-eddy simulations show that surface texture and cross-sectional symmetry govern aerodynamic loads on stationary stranded cables at Re ≈ 1.0×10⁴, with deep grooves disrupting shedding coherence and decoupling mean lateral force from fluctuations.

arXiv:2611.11286v1 Announce Type: cross Abstract: Helically stranded cables in aerial towing systems experience oblique inflow, but are often modeled as smooth cylinders, neglecting three-dimensional cross-stream coupling and surface texture. We perform large-eddy simulations and spectral proper orthogonal decomposition for a smooth cylinder and four stranded cables at four inclinations from $22.5^\circ$ to $90^\circ

$, all stationary, with $Re \approx 1.0 \times 10^4$. Aerodynamic differences are governed mainly by cross-sectional symmetry and strand-scale groove depth. Force-source decomposition shows that surface pressure contributes 94.9%--98.3% of the mean normal force and dominates the mean lateral force. High-symmetry, quasi-circular envelopes maintain balanced circumferential pressure, whereas deep-grooved, low-symmetry t
