dc.description.abstract |
The lower solar atmosphere consists of partially ionized turbulent plasmas harboring velocity field, magnetic
field and current density fluctuations. The correlations amongst these small scale fluctuations give rise to large scale
flows and magnetic fields which decisively affect all transport processes. The three fluid system consisting of electrons,
ions and neutral particles supports nonideal effects such as the Hall effect and the amhipolar diffusion. Here, we study
magnetic transport by ambipolar diffusion and compare the characteristic timescales of the laminar and the turbulent
ambipolar diffusion processes. P s expected from a turbulent transport process, the time scale of the turbulent ambipolar
diffusion is found to be smaller by orders of magnitude as compared with the laminar ambipolar diffusion. The nonlinearity
ofthe laminar ambipolar diffusion creates magnetic structures with sharp gradients which are amenable to processes such
as magnetic reconnection and energy release there from for heating and flaring of the solar plasma. |
