Abstract
En 中文
• Tornado-like vortex energy dissipation is decomposed into viscous and turbulent components. • The spatial distribution of dissipation is linked to axial and radial flow structures. • Axial stretching deformation is a dominant contributor to dissipation in the convergence zone. • Vortex shear deformation in multiple directions drives localized dissipation peaks. • Vortex core eccentricity reveals spatial instability effects on energy loss.
Keywords:
