Teaching content

I will give an instruction of simulation research into multi-hierarchy dynamics on fusion or other plasmas phenomena. Particularly, we will study multi-hierarchy dynamics on non-diffusive radial transport in fusion peripheral plasma.   イメージ図   Figure: Results of the particle simulations of blob dynamics. The blob is thought to cause the non-diffusive radial transport. The left and right panels show the self-consistent current system formed in a blob [Phys. Plasmas 22, 102113 (2015)] and the transport of impurity ion (purple region) by a blob (green tube) [Nucl. Fusion 57, 116008 (2017)].
