Simulations of nonlocal electron transport in cylindrical and spherical thermal waves

In spherical and cylindrical plasmas, the relaxation processes of small amplitude temperature perturbations are simulated with electron Fokker-Planck equation for a wide range of the collision parameter and different charged number Z. The computed electron nonlocal thermal conductivities for spherical and cylindrical plasmas are then compared and analyzed. Based on our sufficient numerical simulations, a practical formula of nonlocal heat flux is presented for a wide range of the collision parameter and different charged number Z, which is in good agreement with the published results.
