| Research Abstract |
Physics involved in a multi-fluid transport code TASK/TX developed by the representative of this research has been in detail elucidated and several models have been newly added or upgraded. Using the code, the close relationship among the radial electric field, the radial current torque and plasma rotation has been clarified. The way to quantitatively estimate the radial current torque for both simulations and experimental analyses has been firmly established by implementing the unique method into the orbit-following code. The novel collisionality-dependent model that can calculate the shielding factor of the beam-driven current has been newly developed.
