Abstract
An equation which includes the non-local effect in the heat flux is
introduced to study the transient transport phenomena. A non-local heat flux,
which is expressed in terms of the integral equation, is superimposed on the
conventional form of the heat flux. This model is applied to describe the fast
responses in the transition from Low confinement mode (L-mode ) to High
confinement mode (H-mode ). A small fraction of non-local component in the heat
flux is found to be very effective in modifying the response against L/H
transition. The transient features of the transport property, which are
observed in the response of heat pulse propagation, are qualitatively
reproduced by the transport simulations based on this model.
