The physical understanding of the transport of heavy impurities, like W, is important for the achievement of practical fusion energy. Among the plasma parameters which affect impurity transport, rotation has only recently received the deserved consideration . In addition to the off-diagonal contribution related to the presence of a radial gradient of the toroidal rotation (usually dubbed roto–diffusion), even in moderately rotating plasmas, centrifugal effects of heavy impurities become non-negligible. This contribution is focused on comparison of model prediction with measured data, including soft X ray tomography.
