Comparing turbulent cascades and heating vs spectral anisotropy in solar wind via direct simulations
The research used direct 3D MHD simulations to test how two different turbulent cascade structures—quasi-2D and radial-slab—affect temperature profiles in the solar wind. The study found that both geometries can generate a temperature decay close to the observed 1/R profile, proving turbulent heating is robust regardless of spectral anisotropy.
