Abstract Text:
High-Z heavy impurities such as tungsten can be sputtered from the ITER-like wall. The tungsten accumulation in the core region of tokamak plasmas poses a significant challenge, as it leads to radiative cooling and dilution of main plasma species. Previous studies have also found that poloidal inhomogeneity of impurities can amplify neoclassical impurity influx. Therefore, we are developing a 2D impurity transport fluid code. This code incorporates the fitting model of the friction (FACIT) to solve the nonlinear parallel momentum fluid equation for impurity neoclassical transport across the entire plasma domain. It is considered self-consistently with various tokamak environments. This approach allows us to understand the relationship between centrifugal force, pressure, and friction by examining the poloidal impurity density structure, with results comparable to NEO and XGC codes.
