Hitachi Industries Co. Ltd., 603 Kandatsu, Tsuchiura, Ibaraki, JAPAN 300-0013 Pellet injection with a bent drift tube is considered as one of the flexible methods to have a variety of fueling locations and injection angles in fusion plasma. Since both pellet mass and velocity greatly affect the plasma properties, mass loss and velocity attenuation of the pellet in the drift tube should be evaluated properly. We focused on the impact of the pellet on the tube wall and numerically estimated the mass loss and the velocity attenuation.
