Abstract:
We have developed an extended kinetic model for the thermal force on test impurity particles in plasmas. This model makes use of a combination of the plasma ion heat flux q GM derived from the generalized moment equations (E. Zawaideh et al., Phys. Fluids 1988 , 31) and the numerical algorithm presented earlier (Y. Homma, A. Hatayama, J. Comput. Phys . 2013 , 250). The applicable condition extends from collisional to weakly collisional plasmas, and weakens when the plasma collisionality decreases. A test simulation is performed assuming a tentative weakly collisional plasma. The results show that it can have a non‐negligible influence on transient impurity transport in a DEMO‐scale tokamak to take into account the effect of plasma collisionality in thermal force modelling.
