Abstract We investigate heat diffusion across a local strong stochastic magnetic field by using eleven low-m perturbed magnetic islands. A maximum stochasticity of 38.82 between two neighboring rational surfaces is attained. The correlation between the effective radial heat conductivity χr and the ratio of the parallel heat diffusion coefficient to the perpendicular coefficient, χ||/χ⊥, is numerically studied and compared with earlier work.
