The role of dust, expected to be important in future large power wall loadings and long operation times, is now recognized for new devices such as ITER. In this context, we study the effect of dust poloidal distributions on plasma dynamics of the plasma edge. We show that in the considered range of dust densities, the poloidal distribution of dust affects only the toroidal velocity, while the poloidal velocity and the radial electric field are defined by the ion-dust friction and thermal forces.
